"Fourteen--fifteen years ago, sir. The master brought me from England where I was employed by the Right Honorable Arthur Sandhurst, sir." "You are now a naturalized American?" "Going on thirteen years, sir." "Come down to my office about noon to-morrow. I want to speak to you then. I haven't time now. Be sure you bring that magpie with you." Drew turned and jerked his thumb toward the front of the library. "Do you understand?" "I do, sir!" "That's all!" exclaimed the detective. "One of you may stand by the door until Mr. Delaney returns. The rest may go downstairs. Remember, no talking to anybody but accredited police officers, who will soon be here." "I'll stand guard!" announced the second-man with a pompous voice. "Nobody'll get by me, sir. I'll 'ave them know I'm right 'ere, sir." Drew backed through the curtains as the second-man was speaking. He dropped them behind him and started another search, which was done in solitude and in silence. He went over everything in the library with the trained eyes of an operative who had learned his profession in many schools. He left deduction and surmise for a later hour. He was after cold facts which might lead to an answer to the riddle. He held, with some slight scorn, the theory of the armchair detective and the puzzle worked out by retrospection. His experience had been, that only through hard work could he expect to find his answer. He had been credited with visiting six hundred laundries in search of a certain mark. He had a note book filled with his failures to find the man he was after. The men he had found caused him no concern whatsoever. They had gone to prison and closed their accounts with him. He applied hard work over the minutes to the case at hand. He went over the body of the aged millionaire. He took scrapings of the blood stains on the floor. He scratched up some few atoms of dried whisky. He examined the bottle. He searched each square inch under and about the body. He went through Stockbridge's pockets and beneath his vest. He tried everything in the way of getting facts which might bear on the case. A tape measure furnished certain distances which were recorded upon the back of an envelope. His data was complete, insofar as he had time to go. He desired to spend at least twelve hours in the library. This could not be. The case would be taken from his hands within minutes. Already there was a stir in the front part of the house. The bell had been ringing for some time. Delaney and the butler had hastened forward to answer it. "The Central Office bunch!" announced the operative, parting the curtains and staring in at Drew. "Here they are, Chief!" The detective stepped briskly out of the room and glided through the foyer hall to the front door. Here Delaney joined him, as steps were heard coming up from the servants' quarters as well as outside. It was as if a raid were in progress.
