Inglise luuraja Mart Männiku (1930–1998) autobiograafia on unikaalne dokument.
Ta langes KGB kätte, kes meelitas ta üle Briti luurest. Männik oli MI6 ebaõnnestunud operatsioonide ohver Eestis aastatel 1951–1955. KGB vastuluure mängis Briti luurega kassi-hiire mängu. Mart Männik, agendi koodnimetusega Otto, maksis rängalt Briti salaluureteenistuse vigade tõttu.

The autobiography of the English spy Mart Männik (1930–1998) is a unique document.
He had fallen into the KGB's hands who turned him round from the British secret service. He was a victim of MI6's unsuccessful operations in Estonia in the years 1951–1955. The KGB counter espionage played with the British as a cat with a mouse. Mart Männik, or as an agent codenamed Otto, paid with a wrecked life for the gross mistakes of the British intelligence secret service.
