"Well?" said Kitson, "our medical friend seems to have got away with it." He sat at the table, nervously drumming with his fingers. "Does the superintendent know everything?" "Nearly everything," replied Beale. "Nearly everything," repeated the superintendent with a smile, "except this great Green Rust business. There I admit I am puzzled." "Even I know nothing about that," said Kitson, looking curiously at Beale. "I suppose one of these days you will tell us all about it. It is a discovery Mr. Beale happed upon whilst he was engaged in protecting Miss----" He looked at Beale and Beale nodded--"Miss Cresswell," said Kitson. "The lady who was present at the murder of Jackson?" "There is no reason why we should not take you into our confidence, the more so since the necessity for secrecy is rapidly passing. Miss Oliva Cresswell is the niece of John Millinborn. Her mother married a scamp who called himself Cresswell but whose real name was Predeaux. He first spent every penny she had and then left her and her infant child." "Predeaux!" cried the detective. "Why you told me that was Jackson's real name." "Jackson, or Predeaux, was her father," said Kitson, "it was believed that he was dead; but after John Millinborn's death I set inquiries on foot and discovered that he had been serving a life sentence in Cayenne and had been released when the French President proclaimed a general amnesty at the close of the war. He was evidently on his way to see John Millinborn the day my unhappy friend was murdered, and it was the recognition of his daughter in the palm-court of the Grand Alliance which produced a fainting-fit to which he was subject." "But how could he recognize the daughter? Had he seen her before?" For answer Kitson took from his pocket a leather folder and opened it. There were two photographs. One of a beautiful woman in the fashion of 25 years before; and one a snapshot of a girl in a modern costume, whom McNorton had no difficulty in recognizing as Oliva Cresswell. "Yes," he said, "they might be the same person."
