“Had he any relatives?” “No, sir, only a brother in Australia.” “Has he heard lately from his brother, do you know?” “Yes, sir; he had a letter only yesterday.” “Well, Freyberger,” said the chief, “have you any question to ask?” “None, sir; but, if you will permit me, I will have that crowd cleared away from the street outside. I would like to examine the road.” “How many men have you outside?” asked the chief of the constable. “Four, sir.” “Go and clear the crowd away. Send for assistance, if necessary.” “If you will permit me, sir,” said Freyberger, “I will go with the constable.” “Do so; I will wait here until your return.” Freyberger left the room. He did not return for some twenty minutes. “Well?” asked the chief, when he returned. “I would like to have a moment’s conversation with you in private, sir.” The doctor had already gone, the chief asked the landlady to withdraw, and Freyberger and he found themselves alone in the room with the corpse. “I have found nothing, sir,” said Freyberger, “I went as a matter of routine. I have, of course, searched narrowly the pavement, the gutter and the road for any possible trace, any dropped article that might possibly furnish a clue. I did not expect to find anything. “Why?” “Because, sir, the man who has murdered Mr Goldberg is not a man to leave clues behind him.” “You know him, then?” “I believe I do, sir. I believe the man who has just committed this crime is no other than Klein, _alias_ Kolbecker, _alias_ Müller.” The chief made an impatient movement. “You must have that man on your brain,” said he. “What on earth connexion can you make between this and the Gyde case?” “One moment, sir; you have had a large experience. Have you ever come across an exactly similar case to this, that is to say, the case of a harmless, elderly gentleman strangled openly in the street for no apparent reason?” “No, I can recall no such case.” “The fact of strangulation alone marks it as a crime by itself. Murderers use every sort of weapon save their own hands.” “The hand, as a rule, is the weapon of the madman.” “Yes?” “Well, sir, I will tell you, in a few words, why I connect this crime with the case of Sir Anthony Gyde.” He then detailed the facts he had learned about the crimes that had followed the murder in the Rue de Turbigo. The chief listened attentively. “So you think—?” he said.
