PROBLEM: What is known for sure about  American military scientist Frank Olson  is that on November 28  1953  the bacteriologist and father of three plunged to  his  death from the thirteenth floor of the Statler hotel in New York City  not long after  he  was secretly drugged with LSD on the orders of  his  CIA superior. Whether  Olson  was pushed  or jumped  or was nudged into committing suicide remains unclear. But indeterminacy with a generous side of conspiracy is catnip to director Errol Morris  who has made either a 241-minute film or a six-part television series depending on where and how you plan to watch it  about the tragedy's long reach into  Olson 's family and America's secretive political culture.
 Olson 's death  and the murk surrounding its cause  cast a defining shadow over the life of his son Eric  whose endless quest to find out what happened that night has pre-empted all other endeavors. The blight spread around his family. His mother became an alcoholic with  the film implies  the active encouragement of one of her husband's colleagues. But Eric  now in his sixties  has arguably been completely derailed by the tragedy. He is the central focus of Wormwood  a hybrid blend of documentary and Cold War thriller that makes The B-Side  Morris's loving portrait of radical photographer Elsa Dorfman earlier this year  look almost straightforward.
Moving back and forth between the 1953 events and 1975  when a Rockefeller commission confirmed that an army scientist had been purposefully drugged with hallucinogens   Wormwood carries us from secret meetings at Deer Lake through the long tail of misery and obfuscation left by  Frank 's death  to Eric's pursuit of the truth all the way to the corridors of power.
In hushed and menacing re-enactments  Peter Sarsgaard  whose mild manner lends itself to all kinds of tonal nuance  charts the decline and fall of  Olson   a patriotic team player whose growing unease about his agency's secretive involvement in biological warfare overseas first worries his boss (a reptilian Tim Blake Nelson) and then moves him to seize the day and use his hapless employee as a guinea pig. By the time  Frank  arrives at the hotel flanked by ambiguously supportive colleagues  he's rapidly unraveling into a gibbering wreck.
Wormwood's breathless  hopped-up style harks back to Morris's 1988 The Thin Blue Line  which called into question a murder verdict and resulted in the release of a wrongly convicted suspect from Death Row. Here the noir markers are writ so large as to verge now and then on self-parody. Morris keeps returning the action to the hotel to act out different angles and competing versions of what happened to  Olson  that night. The hypothetical range between possible perps â  Frank 's boss  his friends  two wordless thugs in fedoras  a CIA allergist played by a sinister Bob Balaban â is narrow enough to make these scenes a touch repetitive if you're watching in one sitting. Certainly they underscore Morris's standing as a lifelong participant observer of American paranoia. For which  it must be said  there is undeniable fodder in the manner of Olsen's going  the secrecy surrounding his death  the ambivalent admissions the Rockefeller Commission along with a dwindling financial settlement that looks suspiciously like hush money to  Olson  and to Morris  and the merrily chuckling presence in old footage of two well-known knowns  Donald Rumsfeld and Dick Cheney.
For all the formal beauty of the re-enactments  the most compelling scenes in Wormwood are the unembellished interviews that Morris â ordinarily an off-screen interlocutor with an appetite for the subtly leading question â is seen conducting across a table with Eric Olson  who waves his arms around with the befuddled intensity of a superannuated schoolboy as he tells his story. Articulate and charming  Eric is a talented collage artist who seems to have sacrificed career and significant relationships to his endless search for justice and truth  even after the case was officially closed and after he contacts investigative reporter Seymour Hersh  who first reported the drugging of  Olson  in The New York Times. Grandiose as always  Hersh insists that  he knows who murdered Frank Olson   but won't say for fear of compromising an anonymous source. We can't tell whether  he 's fibbing either.
A romantic view â and I wouldn't entirely put this past Morris â is that  Olson  is  like  his  interlocutor  an artist with a magnificent obsession that sustains  him  even when it's doomed to failure. But in Wormwood  he  emerges with enormous poignancy as a tragic figure  perpetually stuck in limbo like the father we see tumbling  over and over  to  his  fate.

SOLUTION: Frank Olson

PROBLEM: London (AFP) â Kevin De Bruyne was the creative fulcrum of Manchester Cityâs latest demolition job  while Mousa Dembele inspired Tottenhamâs north London derby triumph.
 Dembele  the midfield maestro
 Mousa Dembele  underlined  his  status as one of Tottenhamâs unsung heroes with a dominant display in their 1-0 win over north London rivals Arsenal. It was Harry Kaneâs latest goal-scoring exploits against the Gunners that took centre-stage at Wembley  but the platform of that success was built by  the industrious Dembele . Embodying Mauricio Pochettinoâs obsession with physical intensity  while more than capable of picking a decisive pass  Dembele out-shone Arsenal in the midfield engine room  earning praise from  his  manager. âLast season  he  played so well  this season  he  suffered a problem in  his  ankle and struggled in pre-season. Now  he  is playing well again â Pochettino said. â He  is an unbelievable player. We have to be careful about  his  fitness. When  he  can train  he  can make this type of performance.â
As if losing 1-0 to struggling Newcastle wasnât enough to have Jose Mourinho seething  the Manchester United boss once again had to suffer the frustration of  Paul  Pogbaâs latest flop. Mourinho had restored Pogba to the starting line-up after dropping him for Unitedâs previous match â a decision inspired by the former Juventus midfielderâs limp efforts in a defeat at Tottenham. But rather than grasp the opportunity to get back in Mourinhoâs good books just days after his boss had defended their relationship  Pogba was again a largely anonymous figure at St Jamesâ Park. By the time he was substituted midway through the second half  United were already trailing  but publicly at least  Mourinho remains supportive. âNo problems â he said when asked about the France international. âI wanted a better way (in midfield) against a side that was defending in a block. I wanted the simplicity of Michael Carrick.â

SOLUTION: Mousa Dembele

PROBLEM: Goldman Sachs highlights two reasons why volatility is now less likely to wreak that type of havoc on the equity market anytime soon.
It was a scary  unprecedented situation for all involved  and traders would be right to feel uncertain about how to proceed. But  Goldman Sachs  is here to put their minds at ease.
 The firm  first uses the chart below to show that the impact of a similar volatility unwinding is the lowest in years. As a result   Goldman  equity derivatives strategist Rocky Fishman says investors don't have to worry about a similar VIX spike for quite some time.
Secondly   Goldman  notes that heading into this week's market reckoning  prices on VIX options were "abnormally high " considering the low level of volatility being reflected by the spot VIX.  Fishman  says this means investors had "priced in some risk of outsized short VIX exchange-traded products causing turmoil like Monday's."
In other words  investors were on edge  even if the traditional VIX measure wasn't reflecting their concern. However   Goldman  says that volatility being implied by VIX options will decline following this week's events. And that means VIX futures will be less primed to explode higher on market turbulence.
What  Goldman  is saying is that the conditions that left the VIX spring-loaded to explode higher are much more subdued now. The market largely got its short-volatility addiction out of its system  and that will help it avoid the type of pain seen earlier this week â at least for now.
