“Now,” said Nick, turning to his first assistant, “the chief thief mentioned last night by name four diamond collections which have been stolen by the syndicate. I remember the main features of the crimes, but of course I know nothing of the details. What I want you to do is to take up these cases and learn all about them. It may be that the hands of the syndicate’s agents may show in some of the deals. It may be that you can trace the finger marks of one person through all the robberies. Locate all the persons, high and low, who might have taken the diamonds in each case.” Chick made a hasty note on his private memorandum, and said: “Have you been to the Wisconsin this morning?” “I have not been out of the office,” was the reply. “You will find something doing up there,” said Chick. “Wait,” said Nick, “let me get the story first hand. You turn this assignment over to Patsy and come with me to the Wisconsin.” The detectives were not long in getting to the hotel. There Nick learned of the occurrences of the night. “Have you heard from Maynard this morning?” he asked of the night clerk, who, pale and distressed, seemingly because of what had taken place, lingered about the corridors instead of going to his room. “He is no worse,” was the reply. “I have just come from there. It seems that he recognized the people who struck him down.” “Does he mention names?” “No; he only says: ‘I know you both. Don’t strike me.’ Strange thing all along.” “How did the assailants get into the room?” asked Nick. “That’s what puzzles me,” was the reply. “I certainly did not let them in.” “Where is the elevator boy who was on watch last night?” “He is asleep upstairs. I told him not to leave the building.” “Bring him down.” But the elevator boy was not upstairs. He was not in the hotel at all. “I am sorry for this,” said the clerk, “because I wanted to clear myself in another matter.” Nick scented more trouble. “What is it?” he asked. “Well,” said the clerk, evidently very much frightened, “you gave me a bundle last night, and asked me to keep it until you personally came for it. Did you get it during the night?” Nick saw what the new trouble was, and was angry, but gave no evidence of the fact. “I did not,” he replied. “Well, the boy gave the bundle out last night. He stated that you called for it.” “At what time was it given out?” “Quite early in the morning.” “After the assault on Maynard?” “Yes, sir; so he said.” “Where were you?” “I dozed off and left the boy in charge.” “Is it usual to leave a boy on watch?” “No, sir, only——” “Never mind that now. What did the boy say about it?” “Just said you came after the package.” Nick was not satisfied that the clerk was telling the truth. He was very much annoyed at the loss of the clothes. “I did not think you had been here,” said the clerk, “and was angry with the boy.” “And you scolded him, eh?” “Yes, sir.” “Do you think he will return?” “I do not, sir.”
