“You see,” explained Moris Klaw, later, to his wondering audience, “this girl--I have yet to find out who she is--was perhaps married to Mr. Chinje. He would, of course, have deserted her directly he returned to India. But here at the Astoria she was known as Mrs. Chinje. Who would have been the losers by the robbery? The insurance company, if I do not mistake the case. For the Gaekwar, through his representative, Chinje, had the diamond insured for all the time it was his property and in England, and the Committee had it insured from the time it became their property. It had become their property. The Gaekwar would have got his check. He gets it now; it is in Chinje’s pocket-case. The city would have lost its Blue Rajah, and the insurance company would have paid the city for the loss! “The next office along the corridor from Mr. Anderson’s is the Central London Electric Lighting Company. Many consumers call. Mrs. Chinje was not suspected of any felonious purpose when she was seen in that corridor--and she was seen by a clerk and by an engineer. After my mental negative had told me of a pretty young lady of whom the thief thinks at the moment of his theft, I went to inquire--you recall?--if such a one had been seen near the office. “From the first my suspicions are with Chinje. The emotions have each a note, distinct, like the notes of a piano, though only audible to the trained mind. Both Isis and myself detect from Chinje the note of _fear_. I arrange, then, that he remains. My talk of examining the Gaekwar’s writing is a ruse. It is Chinje’s apartment and the fair lady I expect to find there that I am anxious to see. “Then, in spite that he is the most cool of us all, I see that he suspects me and I have to hold him fast; for, if he could have got first to his room and hidden the parrot cage, where had been our evidence? Indeed, only that I have the power to secure the astral negative, there had been no evidence at all. There is a third accomplice--him who howled in the courtyard; but I fear, as he so cleverly vanished, we shall never know his name. “And how was it done, and why did this someone howl?” Moris Klaw paused and looked around. We awaited his next words in tense silence. “He howled because Chinje had looked out from the window (which, though hidden, the howler was watching) and made him some signal. The signal meant: ‘The Blue Rajah has been placed upon the table--_howl!_’ “The one below obeyed, and the Committee, like foolish sheep--yes, gentlemen, like no-headed cattle things!--flocked to the window. But Chinje did not flock with them! Like a deft-handed conjurer he was at the table, the diamond was in the little rubber purse held ready, and Mrs. Chinje, with her large handbag open, was waiting outside the door, in the corridor, like some new kind of wicket-keeper. Chinje tossed the diamond through the little square ventilator!
