As I look back now on the sensational events of the past months since the great European War began, it seems to me as if there had never been a period in Craig Kennedy's life more replete with thrilling adventures than this. In fact, scarcely had one mysterious event been straightened out from the tangled skein, when another, even more baffling, crowded on its very heels. As was to have been expected with us in America, not all of these remarkable experiences grew either directly or indire...

THE PERUVIAN DAGGER "There's something weird and mysterious about the robbery, Kennedy. They took the very thing I treasure most of all, an ancient Peruvian dagger." Professor Allan Norton was very much excited as he dropped into Craig's laboratory early that forenoon. Norton, I may say, was one of the younger members of the faculty, like Kennedy. Already, however, he had made for himself a place as one of the foremost of South American explorers and archaeologists. "How they got into the ...

I am not by nature a spy, Professor Kennedy, but—well, sometimes one is forced into something like that." Maude Euston, who had sought out Craig in his laboratory, was a striking girl, not merely because she was pretty or because her gown was modish.

He handed me a clipping from the evening edition of the Star and I quickly ran my eye over the headline: "THE CLUTCHING HAND" WINS AGAIN NEW YORK'S MYSTERIOUS MASTER CRIMINAL PERFECTS another COUP CITY POLICE COMPLETELY BAFFLED "Here's this murder of Fletcher, the retired banker and trustee of the Universi...

Until I receive those materials from Doctor Leslie to make the poison tests, considered Kennedy, as we walked slowly the few blocks to the laboratory, "I can't see that there is much I can do but wait." In his laboratory, he paused before his well-stocked shelves with their miscellaneous collection of books on almost every conceivable subject. Absently he selected a volume. I could see that it was one of the latest translated treatises on this new psychology from the pen of the eminent sci...
