Context paragraphs:
Murder of Olive Balchin: Olive Balchin (c. 1906 – 20 October 1946) was a British murder victim whose body was found near a bomb site in Manchester, England.  The murder weapon, a bloodstained hammer, was found nearby.  After a lengthy investigation, police were given a description of a man who purchased a hammer from a local shopkeeper, which was similar to the description that eyewitnesses provided of a man last seen in the company of Balchin on the night of her murder.  Based on this information, police questioned Walter Graham Rowland, a man who had been convicted in 1934 of murdering his two-year-old child.  His death sentence for that crime had been commuted after serving eight years, due to the onset of World War II and the need for able-bodied men.

Hourglass figure: The hourglass is one of four female body shapes.  The other shapes are the rectangular, inverted triangle, and spoon.  The hourglass shape is defined as a woman whose body measurements, the circumference of the bust, waist, and hips, are a wide bust, a narrow waist, and a wide hip that has similar measurements to that of the bust.  This body shape is aptly named for its resemblance to that of an hourglass where the upper and lower half are wide while the portion at middle is narrow in circumference making the ratio wide-narrow-wide.  Women who exhibit the hour glass figure are proven to be more admired which puts pressure on other women who are less attractive to strive to achieve the hour glass figure.  This in return leads to body dissatisfaction which can cause eating disorders in young women from all over the globe.

The Man Who Never Was: The Man Who Never Was is a 1956 Second World War film, based on the book of the same name by Lt. Cmdr. Ewen Montagu and dramatising actual events.  The film was directed by Ronald Neame and starred Clifton Webb, Gloria Grahame and Robert Flemyng.

Glyndwr Michael: Glyndwr Michael (4 January 1909 – 24 January 1943) was a homeless Welsh man whose body was used in Operation Mincemeat, the successful Second World War deception plan that lured German forces to Greece prior to the Allied invasion of Sicily.

Nathan F. Cobb: The Nathan F. Cobb was a three-masted schooner named after the shipbuilder and founder of Cobb’s Salvaging Company whose many rescues of stranded ships help lead to the formation of the United States Life-Saving Service.  Despite its namesake's history of shipwreck rescues, the "Nathan F. Cobb" capsized in heavy seas on 1 December 1896 en route from Brunswick, Georgia to New York with a cargo of timber and cross ties.  The cook and a shipmate drowned when they were swept overboard in violent seas.  The crew righted the vessel by removing the three masts and they drifted for four days until they became grounded on a sandbar off Ormond Beach, Florida.  Rescue attempts led to the drowning of volunteer Ferd Waterhouse, whose body was never recovered, but no other crew members were lost.  A plaque commemorates Ferd Waterhouse’s rescue efforts.  The Cobb Cottage, a structure built using materials salvaged from the ship, is part of Ormond Beach’s Historic Trail.

The Incredible Melting Man: The Incredible Melting Man is a 1977 American science fiction horror film directed and written by William Sachs.  The plot concerns an astronaut whose body begins to melt after he is exposed to radiation during a space flight to Saturn, driving him to commit murders and consume human flesh to survive.  During post-production, the producers reshot scenes without Sachs' participation.  The film starred Alex Rebar as the main character, alongside Burr DeBenning as a scientist trying to help him and Myron Healey as a United States Air Force general seeking to capture him.  While writing and shooting, Sachs was influenced by "The Night of the Living Dead."  With the changes by the producers, the final film has been described as a remake of "First Man into Space" (1959), which in turn was directly influenced by "The Quatermass Xperiment", even though Sachs had never seen either of those films.

Operation Mincemeat: Operation Mincemeat was a successful British disinformation strategy used during the Second World War.  As a deception intended to cover the 1943 Allied invasion of Sicily, two members of British intelligence obtained the body of Glyndwr Michael, a homeless man who died from eating rat poison, dressed him as an officer of the Royal Marines and placed personal items on him identifying him as Captain (Acting Major) William Martin.  Correspondence between two British generals which suggested that the Allies planned to invade Greece and Sardinia, with Sicily as merely the target of a feint, was also placed on the body.
