"The tobacco was recommended by old Hosko," he said, "and you'll find nothing violent in it, no matter what you find in my conversation."

"What put you into such a frame of mind, anyway? Something happened?"

But Ashton-Kirk shook his head.

"I don't know," said he. "In fact, I have been strangely idle for the last fortnight. The most exciting things that have appeared above my personal horizon have been a queer little edition of Albertus-Magnus, struck off in an obscure printing shop in Florence in the early part of the sixteenth century, and a splendid, large paper Poe, to which I fortunately happened to be a subscriber."

A volume of the Poe and the Albertus-Magnus were lying at hand; Pendleton ignored the dumpy, stained little Latin volume; its strong-smelling leather binding and faded text had no attractions for him. But he took up the Poe and began idly turning its leaves.

"It is a mistake to suppose that some specific thing must be the cause of an action, or a train of thought," resumed the other, from the comfortable depths of his chair. "Sometimes thousands of things go to the making of a single thought, countless others to the doing of a single deed. And yet again, a thing entirely unassociated with a result may be the beginning of the result, so to speak. For example, a volume of Henry James which I was reading last night might be the cause of my turning to the literature of assassination this morning; your friendly visit may result in my coming in contact with a murder that will make any of these," with a nod toward the scattered volumes, "seem tame."

Pendleton threw away his cigarette and proceeded to roll another.

"It is my earnest desire to remain upon friendly terms with you, Kirk," stated he, with a smile. "Therefore, I will make no comment except to say that your last reflection was entirely uncalled for."

Lighting the cigarette, he turned the tall leaves of the beautiful volume upon his knee.

"This edition is quite perfection," he remarked admiringly. "And I'm sorry that I was not asked to subscribe. However," and Pendleton glanced humorously at his friend, "I don't suppose its beauty is what attracts you to-day. It is because certain pages are spread with the records of crime. I notice that this volume holds both 'The Murders in the Rue Morgue' and the 'Mystery of Marie Roget.'"
