“A twenty-thousand-dollar diamond necklace was stolen from a private car two nights ago; there was an express car robbery on Monday of this week; and a sleeping car was thoroughly and systematically looted the night before. True, it is mere conjecture to connect the Hawk with these in any way, since the gang that has been operating in this neighbourhood has proved itself quite capable of all and more than this without any outside and highly specialised assistance, and it would appear is in no whit inferior in resource and devilish ingenuity to the best, or worst, that Sing Sing has to offer in the shape of this so-called Hawk; but, out of conjecture, one question naturally suggests itself.

“Granting the presence of the Hawk, is he here as a rival of the criminals of whose existence we are already only too well aware, or is he one of them through old-time associations before Sing Sing put a temporary check upon his activities?”

“'mtlky'—stroke at five. Two-three-one tonight,” he said aloud.

Without pause, without hesitation, without the slightest indication of spacing to break its continuity, the sounder rattled on—and finally, as abruptly as it had begun, it stopped.
