“There’s every reason,” he snapped.

“Why should you interest yourself in the Gables?”

“Does no explanation occur to you?”

“None whatever; to me the whole thing smacks of stark lunacy.”

“Then you won’t come?”

“I’ve never stuck at anything, Smith,” I replied, “however undignified, when it has seemed that my presence could be of the slightest use.”

As I rose to my feet, Smith stepped in front of me, and the steely gray eyes shone out strangely from the altered face. He clapped his hands upon my shoulders.

“If I assure you that your presence is necessary to my safety,” he said—“that if you fail me I must seek another companion—will you come?”

Intuitively, I knew that he was keeping something back, and I was conscious of some resentment, but nevertheless my reply was a foregone conclusion, and—with the borrowed appearance of an extremely untidy old man—I crept guiltily out of my house that evening and into the cab which Smith had waiting.

The Gables was a roomy and rambling place lying back a considerable distance from the road. A semicircular drive gave access to the door, and so densely wooded was the ground, that for the most part the drive was practically a tunnel—a verdant tunnel. A high brick wall concealed the building from the point of view of any one on the roadway, but either horn of the crescent drive terminated at a heavy, wrought-iron gateway.
