Who put Bella in the Wych Elm? a tree. He died in the hospital before the body in the wych elm was found. The likelihood of this being the correct explanation is questioned because Una Mossop did not come forward with this information until more than 10 years after Jack Mossop's death. Another theory comes from an MI5 declassified file about Josef Jakobs - the last man to be put to death in the Tower of London on 15 August 1941. An Abwehr agent, he parachuted into Cambridgeshire in 1941 but broke his ankle when landing and was soon arrested by the Home Guard. On his person
Karel Richard Richter the expired Czechoslovak passport in his possession (which was in his own name). Richter was sent to Camp 020 where he was interrogated by officers of MI5. Richter was a difficult agent to break and it was only when he was confronted with fellow spy Josef Jakobs that Richter began to crack. Richter revealed the true purpose of his mission, to check up on agent Wulf Schmidt. Richter was charged with espionage under the Treachery Act 1940. He was tried in camera at the Old Bailey and found guilty on 24 October 1941. He was sentenced to death by hanging.
