Operation Diver was the British codename for countermeasures against the V-1 flying bomb campaign launched by the German Luftwaffe in 1944 against London and other parts of Britain.
 "Diver" was the codename for the V-1 itself.
 Modes of defence used against V-1s included anti-aircraft guns, barrage balloons, and fighter aircraft; also double agents planted false information about the success of targeting.
 Anti-aircraft guns proved the most effective form of defence in the later stages of the campaign, with the aid of radar-based technology and the proximity fuse.
 The bombing campaigns ended by the middle of 1944.
The Cambridge Spy Ring was a ring of spies in the United Kingdom, who passed information to the Soviet Union during World War II and was active at least into the early 1950s.
 Four members of the ring were originally identified: Kim Philby (cryptonym: Stanley), Donald Duart Maclean (cryptonym: Homer), Guy Burgess (cryptonym: Hicks) and Anthony Blunt (cryptonyms: Tony, Johnson).
 Once jointly known as the Cambridge Four and later as the Cambridge Five, the number increased as more evidence came to light.
St. Ermin's Hotel is a four-star central London hotel adjacent to St James's Park underground station, close to Westminster Abbey, Buckingham Palace and the Houses of Parliament.
 The Grade II-listed late Victorian building, built as one of the early mansion blocks in the city is thought to be named after an ancient monastery reputed to have occupied the site pre-10th century.
 Converted to a hotel in 1896–99, it became during the 1930s, through the Second World War and beyond, a meeting place of the British intelligence services, notably the birthplace of the Special Operations Executive (SOE), and where notorious Cambridge Five double agents Philby and MacLean met their Russian handlers.
"Trust Metric" is the season premiere of the fourth season of the American television show "Numb3rs".
 Written by series writer Ken Sanzel, "Trust Metric" is set five weeks after the events in "The Janus List".
 In "Trust Metric"'s story, a Federal Bureau of Investigation (FBI) team attempts to find a pair of double agents, one of them a former teammate, who have escaped from prison.
 The story continues the events that began in "The Janus List".
Ronald Thomas "Ronnie" Reed (8 October 1916, St Pancras, London – 22 January 1995, Dulwich, London) was a BBC radio engineer who became an MI5 officer in 1940, and ran double agents during World War II.
St Katharine's by the Tower—full name Royal Hospital and Collegiate Church of St. Katharine by the Tower—was a medieval church and hospital next to the Tower of London.
 The establishment was founded in 1147 and the buildings demolished in 1825 to build St Katharine Docks, which takes its name from it.
 It was re-established elsewhere in London and 123 years later returned once more to the East End.
 The church was a Royal Peculiar and the precinct around it was an extra-parochial area, eventually becoming a civil parish which was dissolved in 1895.
 The Royal Peculiar survives to the present day as the Royal Foundation of St Katharine.
The Nashville Terminal Subdivision is a railroad line owned by CSX Transportation in the U.S. State of Tennessee.
 The Subdivision is broken up into 5 sections all in Nashville, Tennessee.
 The northern part of the Terminal is in Madison, Tennessee at milepost 000/0BA 174 on the southern end of the Ex-L&N Mainline Subdivision at Monfort.
 Disptach for the Mainline Sub is known as "LD" which is part of the Cincinnati Division.
 From here in Madison begins the double track that stays for another 22 miles south to Brentwood, Tennessee.
 At milepost 000/0BA/00H 176.6, the famous Johnny Cash "Amqui" location where the Ex-L&N Evansville, Indiana line, the Henderson Subdivision meets with the Terminal.
 Dispatch for the Henderson Sub is known as "SA" and operates on AAR58.
 There are two crossings near each other, Williams Ave and Nesbitt Lane at Amqui.
 From here the Terminal goes south about 2 miles to the Nashville National Cemetery to the first major location, known as Ekin, 000179, where there is a cross over track from number 1 to number 2 track (left to right track).
 There is also the first EDD (Defect Detector) at 000179.1.
 Few more miles southward, the next major location appears.
 At 000181.0, Maplewood is a major location for the Terminal.
 From here the regular Terminal goes south to swap crews at Kayne Ave, and the right side, Radnor Cutoff, detours the city and gives yard departures and arrivals direct access to and from Radnor yard to cities like Louisville and Chicago.
 The Cutoff runs from Maplewood to Shelby Park double track.
 From Shebly the track converges into one to pass the historic Shelby bridge, then it opens back to double track.
 From there, the cutoff hits the Intermediates at 0BA187.0 known as Chicken Pike.
 The Radnor Cutoff carries the L&N mainline classification of "0BA" but meets the main at the same milepost from the Terminal.
 At Chicken Pike, trains are staged to await arrival to Radnor yard.
 Once they get clearance, speed is decreased to 15, and at 0BA188.1 the EDD (Defect Detector) sounds for departures and arrivals.
 This location is known as North Radnor.
 The right track diverging from the #2 is known as A-1, it is for departure trains to Chattanooga and Atlanta.
 The left track which goes west from the #1 is known as A-2, and serves as a departure track to Memphis, and if the cutoff is out of service, all northbound departures.
 The interesting piece of Maplewood is the crossovers that are there to move trains from the Cutoff to the Main.
 Both lines remain double track for a while.
 The main runs south for 2 more miles until the Intermediate signals at 000183.0.
 Commonly trains will stop before Delmas Ave when Kayne Ave is at capacity and await dispatch permission before moving south.
 From here, the main continues south until the CR Cumberland River Swingbridge, where the main converges into a single track shortly to cross the bridge.
 At this point, trains had been running at track speed of around 40.
 From the drawbridge into town, speed is reduced to around 10.
 After the bridge is passed, the main returns to double track in downtown.
 On the #1 track about a half a mile south, another connecting track is present.
 This is the Wye track that connects the main with the Bruceton side, while rarely used for mainline trains, locals and river jobs use it.
 The location is known as 8th Avenue or 8th Avenue Wye.
 The main then runs down to Kayne Ave, the central hotbed of all Nashville thru traffic.
 The Memphis, Tennessee Ex-L&N Bruceton Subdivision meets with the Terminal.
 The Bruceton Sub begins at Church Street at 00N0.0.
 The line then runs single track until 00N0.7 "11th Avenue" where it turns into double track and also meets the aforementioned, Wye track.
 The Bruceton line then goes southwest a while to the next signals, at "Shops".
 Now speed has been increased.
 The line is still double track until "Sellars", where speed is increased to 40 and jurisdiction transferred to the SD Dispatcher.
 For a short time, 4 main tracks are present and an additional fifth track for switchers and yard movements.
 The tracks from left to right in Kayne Ave are as follows: 100, 99, 98, 12, 3.
 The Kayne Ave yard is also here in this area, which houses some frieght and some switcher engines.
 The tracks to the old shed are covered and removed.
 The Union Station is not an active station, but a historic hotel.
 Crew change usually occurs at the "walkway" which is under the Demombreun St bridge by the Kayne Ave Tower.
 This is also where the Ex-NC&StL Chattanooga Subdivision begins.
 Then tracks run south to Fogg St/South End where things get complicated.
 At milepost 000/0BA/00J187 the 98 track merges into the 12 track, making for 3 tracks now.
 There is a crossover from 99 to 12, also a crossover from 12 to 3.
 About 2/10ths of a mile down the 99 merges into the 12 track reducing the tracks back to the regular double.
 About 4/10ths of a mile down the line from Fogg St, 000187.4, Oak St, is a crossover track from #2 to #1 (the track names are no longer 3 and 12, but are back to regular names).
 When trains use this crossover northbound, such as Memphis bound trains from the A-2 line, they refer to it as "Long Lead".
 And now, the Terminal splits into two parts.
 The right side turns into a single track shortly, and will become the Chattanooga Subdivision, and the left side runs south to Brentwood.
 The right track runs single shortly until double track for a while.
 This begins part of the Chattanooga Sub or J-Line.
 The #2 meets with the A-2 connection track at 00J2.2 known as A-2.
 Speed is now increased to 40.
 Commonly northbounds will stage at 4th Ave on the #1 to await clearance.
 Now about a mile down the #1 meets the A-1 connection line.
 At 00J3.6 known as A-1.
 Further down the double track ends at Glencliff (00J4.9).
 Now it runs single for three miles until it hits Danley, which has the D Line connection track, which is an arrival track for incoming Radnor trains from the J Line.
 At Danley, the Terminal ends but the same dispatcher handles traffic, "SC".
 At Oak Street, our main terminal line goes south two miles to 000189.0 known as Criaghead or Vine Hill.
 There is a crossover here from #1 to #2 track.
 And there is also a connection/delivery track to the Nashville and Eastern Railroad which connects the Tennessee Central Railroad Museum to a major railroad.
 Trains sometimes stop on the #2 before Craighead if they are waiting to enter Radnor yard.
 Sometimes trains wait on the #1 at the Berry Road crossing if they await arrival to Kayne Ave. At this point, speed has been increased to 30 from 10.
 Moving south, the line hits Radnor Yard at 000192.
 The #2 track meets the E-Line arrival track which most Memphis trains and locals use.
 The B-Line which meets the #1 track is used for departures out of the C yard and local jobs.
 At Mayton, 000192.3, the B line meets the #1 track, and there is a crossover track from #2 to #1.
 Speed is now at 40.
 2 miles south, at 000194.0, South Radnor, the next intersection is present.
 This is where the Radnor A yard meets the main.
 There is a single departure/arrival track that meets the #2 track along with a crossover from #1 to #2 track.
 Commonly, the #2 track south of the signals is used to halt trains.
 This location is known as TVA, because of the power station that is adjacent.
 From here the Terminal runs about 2.5 miles south until we hit the southern tip.
 The tracks converge onto one single main, at 000/0BA196.6 known as Brentwood.
 Speed is increased to 50 and jurisdiction to the S.E. dispatcher.
 The right track is the main, S&NA North, while the left track is the Nashville Subdivision which runs to Columbia and exchanges freight with the TSRR.
 The Nashville Terminal Subdivision is one of the busiest locations on the CSX network, and one of the most important.
A Turkish name consists of an "ad" or an "isim" (given name; plural "adlar" and "isimler") and a "soyadı" or "soyisim" (surname).
 Turkish names exist in a "full name" format.
 While there is only one "soyadı" (surname) in the full name there may be more than one "ad" (given name).
 Married women may carry both their maiden and husband's surnames.
 The "soyadı" is written as the last element of the full name, after all given names (except that official documents often use the format "Soyadı, Adı").
Operation Blossom was a covert operation that was formed by the Office of Policy Coordination (OPC) in 1950.
 Although one of many Korean War strategies, the main intent of this operation was to create a resistance during war times in North Korea.
 The OPC took refugees that emerged from North Korea and provided them necessary information and supplies to complete the operation.
 These groups of refugees would return to North Korea and attempt to infiltrate the Communist country.
 The hopes of success lied in the ability of the civilian population to go along with the resistance.
 The results of the operation were varied: some of the Blossom operators could not be contacted again while some could be reached until 1951.
 The following year there was no indication that the operation was still in place and functioning.
 A conclusion was made that all the members were acting as double agents, captured, or were known operators and could no longer create a resistance.
 In September 1952, the suspicion was confirmed that the remaining operators were working for both sides and were terminated.
 It was in late 1952 that this operation was officially over.
St Mary Axe was a mediaeval church in the City of London.
 Its full name was "St Mary, St Ursula and her 11,000 Virgins", and it was also sometimes referred to as "St Mary Pellipar".
 Its common name (also "St Mary" [or "Marie"] "at the Axe") derives from the sign of an axe over the east end of the church.
 The church's patrons were the Skinners' Company.

Question: What is the full name of one of the double agents who met Russian handlers at St Ermin's Hotel in London?
Answer: Kim Philby
