THE affair of Mary Keen was never forgotten by Robert Karl Kressholm. He was a good hater, as Mr. J. G. Reeder was to say of him one day.Yet it was an odd circumstance that Mary, dead and buried in Westbury Churchyard, should remain as a raw place in the mind of a man who was, to all appearance and certainly by protestation, madly in love with a child-she was little more-who was twenty years his junior. But Bob Kressholm was like that. He was vain, had complete and absolute confidence in his own excellences. He might congratulate himself that he was young at thirty-seven and looked younger; that he was good-looking in an instantly impressing way and looked little older than at eighteen, when Mary had chosen Red Joe Brady in preference to himself.Mary was dead of a broken heart-she passed three days after Joe had been released from a short-term sentence in Dartmoor. If Bob could have found her he would have offered consolation of sorts, but Joe had very carefully hidden her and his boy.Kressholm never went to prison. He was too clever for that. Banks and jewellers' stores might become impoverished in a night, but "the Guv'nor" could not be associated with the happening. He was, he believed with reason, the greatest organiser in what is picturesquely described as "The Underworld." Nobody had ever brought a mind like his to the business of burglary. He had his own office and plant in Antwerp for the reconstruction of stolen goods. In Vienna a respectable broker handled such bonds and negotiable stock as came his way. He could boast to such intimates as Red Joe that he was "squawk-proof" and was justified in the claim. He came down to Exeter, where Haddin's Amusement Park was operating, partly to see and partly to dazzle Joe out of his dull but respectable mode of living. A big Rolls limousine was an advertisement of his own prosperity.He did not see the balloon ascent, but the parachute dropped square in the road before his car, and the chauffeur had just time to pull up on the very edge of a tangled mass of cord, silk envelope and laughing girlhood."Where the devil did you come from?""Out of the everywhere," she mocked him.She wore a boy's trousers, a blue silk shirt and a beret-an unusual head-dress in those days-and she was lovely: golden-haired, fair-skinned and supple.This was Wenna, daughter of Lew Haddin.He drove her to the fair and delivered her to her father. Having come for the day, he stayed for the week; Red Joe had a bed put for him in his own caravan. Joe had a second van-a motor caravan, but this was not in the fair-ground. It was garaged in the town. His guest heard about this and drew his own conclusions-at the moment he was not interested in Red Joe's dangerous hobby.And every day he grew more and more fascinated by the girl. He brought flowers to her, which she accepted, a jewelled bracelet, which she refused. Fat Lew Haddin offered lame apologies, for he was a good-natured man who gave things away rather readily and would have married off his daughter to almost anybody rather than worry.Red Joe added to his unpopularity and stirred up all the smouldering embers of hatred by speaking very plainly to his guest."She's only a kid, Bob, and what have you and I to give any woman? The certainty of getting her a pass on visiting day and the privilege of writing her a letter once a month."
