blued-steel, highly tempered instruments--a compact, powerful burglar's kit. The slim, sensitive fingers passed with almost a caressing touch over the vicious little implements, and from one of the pockets extracted a thin, flat metal case. This Jimmie Dale opened, and glanced inside--between sheets of oil paper lay little rows of GRAY, ADHESIVE, DIAMOND-SHAPED SEALS. Jimmie Dale snapped the case shut, returned it to its recess, and from another took out a black silk mask. He held it up to the light for examination. "Pretty good shape after a year," muttered Jimmie Dale, replacing it. He put on the belt, then his vest and coat. From the drawer of his dresser he took an automatic revolver and an electric flashlight, slipped them into his pocket, and went softly downstairs. From the hat stand he chose a black slouch hat, pulled it well over his eyes--and left the house. Jimmie Dale walked down a block, then hailed a bus and mounted to the top. It was late, and he found himself the only passenger. He inserted his dime in the conductor's little resonant-belled cash receiver, and then settled back on the uncomfortable, bumping, cushionless seat. On rattled the bus; it turned across town, passed the Circle, and headed for Fifth Avenue--but Jimmie Dale, to all appearances, was quite oblivious of its movements.

The police had worked themselves into a frenzy over the Gray Seal, the papers had grown absolutely maudlin--and she had written, in her characteristic way: Things are a little too warm, aren't they, Jimmie? Let's let them cool for a year. Since then until to-night he had heard nothing from her. It was a strange compact that he had entered into--so strange that it could never have known, could never know a parallel--unique, dangerous, bizarre, it was all that and more. It had begun really through his connection with his father's business--the business of manufacturing safes that should defy the cleverest criminals--when his brains, turned into that channel, had been pitted against the underworld, against the methods of a thousand different crooks from Maine to California, the report of
