Charles Monro descends the train and sees Douglas with his son Christopher at the end of the wharf at Winchester Chesil station. Instinctively, he squeezes a precious black satchel against him. His mind is suddenly plunged into the past; in an instant he recalled London at the end of the nineteenth century that knew his father James Monro responsible for Scotland Yard, and especially in 1888, year of the terrible murders of prostitutes. At that time, some parts of London were slums where men, women and children were crowded together in miserable conditions, poor souls who had been tormented by life, working in factories, workshops and foundries. It was the battlefield of distress, with its dirty avenues, its frightful alleyways, and its dark alleyways, and, in particular, that of Whitechapel. Douglas helps his brother to settle in the vehicle, while the six-year-old Christopher jumps in the back seat. The car starts in the direction of the family home. Charles is sixty-one years old, but he is very ill and he wants to hand over to Douglas the contents of the precious black satchel. After a cup of tea and a few moments of exchange, the two men headed for the Douglas office, located on the ground floor of the house. Charles opens his satchel and takes out the documents handed to him, just before his death in 1920, by the illustrious chief commissioner, James Monro of Scotland Yard. Douglas feverishly reads a case concerning the homosexuality of the Reverend J.K Stephen, who had posed problems of morals at the colleges of Winchester and Trinity at Cambridge. An appendix mentions the homosexuality of Montague John Druitt when he was educated in Winchester, then his dismissal when he taught Blackheath boys. The end of the narrative indicates that the body of John Druitt discovered in the Thames in December 1888 was certainly a murder linked to a homosexual encounter. In spite of Inspector Abberline's doubts, James Monro himself insisted that this file be classified in suicide cases. Charles takes out one last leaf, and says in a voice from beyond the grave;
“James Monro asked me to pass on to the younger son of the family this precious document, which reads Highly private memoranda. This note explains what happened during the fall of terror in 1888. James Monro gives in this memorandum the true identity of Jack the Ripper.”
After a few minutes of silence, during which Douglas reads the contents of this memorandum...
“No! Charles, burn this document, Charlie, burn it all! The name of the Whitechapel murderer can not be revealed, no one should know who Jack the Ripper was.”
Christopher who plays under the window, is concerned about his father's cries. He discreetly walks away from the house, not understanding that these documents are compromising for the honour of his grandfather James Monro, but also for all his family. This highly private Memorandum will probably be destroyed ... no one will know the truth about Jack the Ripper ... or not?
