of his method of escape concealed in false bottoms. Although his parcels arrived, no prisoner attempted to repeat his methods. As an escaped prisoner of war, he was exempt from conscription and his views had begun to drift towards pacifism. He wrote a memoir of his experiences, To Ruhleben – And Back, and published in 1916. Because the war was still on at that time, Pyke omitted some details of his escape from his account. To Ruhleben – And Back was republished in 2002. In March 1918, Pyke met Margaret Amy Chubb, they were married within three months of meeting. Between the wars Malting House School Between the First and Second World Wars, Pyke attempted a number of money-making schemes, speculating on the commodity market, using his own system of financial management and working through a number of different stockbrokers to avoid attention and higher stock broking charges. The Pykes had a son, David Pyke (1921–2001), and Pyke became preoccupied by the question of his son's education.

The Malting House School was forced to close, Margaret Pyke had to take a job as a headmistress's secretary; she left Geoffrey although they were never divorced.
