“I wish he had gone down again!” cried Maynard, starting from his chair. “He lost his life by going on! Can nothing be done, Mr. Carter? Is he past all hope of recovery?” Nick dismissed the elevator boy and turned to the agitated young man. “Don’t give way to your emotions now,” he said. “We have much to do if the murderer is ever brought to justice and the diamonds recovered.” “Never mind the diamonds,” said Maynard. “I wish I had never set eyes on them! First my poor uncle, and now my best friend! The devil is in the diamonds! I hope I shall never see them again.” “Are you strong enough to remain here while I take a look at the body and the room? If not, you would better sit in the office.” “Oh, yes, I’ll remain here. Poor Henry! You don’t know what it is to lose a chum like that.” Nick approached the body and lifted the head from the table. There was no blood in sight. But just over the heart was a faint stain. The detective opened the shirt and saw a tiny puncture in the breast. The dead man had been stabbed with some slender weapon. The wound was exactly over the heart. Nick gazed long and thoughtfully at the still figure. He did not understand how the wound could have been made so exactly over the vital spot. If Townsend had resisted, such a mode of murder would have been impossible. Then a light came to the wondering detective. He bent forward and laid his face close to that of the dead man. “I thought so!” he then muttered. “What is it?” asked Maynard. “A spray of chloroform was thrown into Townsend’s face, and the wound was made while he was dazed, if not quite unconscious.” “But if the murderer had him under the influence of the drug, why did he not permit the drug to do the work? This stabbing seems brutal and unnecessary.” “I can’t understand that part of it myself,” said Nick. “However, we shall know more of the details before long.” “What sort of a weapon was it?” asked Maynard. “The cut is a tiny one.” “It might have been made with a hatpin,” said Nick. “Men don’t carry hatpins about with them,” said Maynard. “This murder,” replied Nick, “was committed by a woman.” “A woman!” echoed Maynard. “Exactly, by a woman disguised as a man. That may be why the young man was dazed with a spray of chloroform before the fatal blow was struck. The woman was not strong or daring enough to take the risk of determined resistance.” “But how do you know that it was a woman who was here? The clerk said nothing about that.” “The clerk was deceived. See here! This blue ribbon comes from the front of a woman’s undervest. In the haste of dressing in Townsend’s clothes, the ribbon broke and she tossed it aside. There are other things that tell me it was a woman, sure enough.” “Think of a woman doing a thing like this!” cried Maynard. “Horrible crimes have been committed by women,” said Nick, laying the cast-off clothing of the murderer on the table and drawing up a chair.
