"Oh, it has nothing to do with the law," he replied with an odd smile.
"In fact, it's a little matter in which we are--well, you might say--
outside the law."

I gave a gasp at this disturbing suggestion, and Henry chuckled as he
saw the consternation written on my face. Then he rose and said:

"Come, the boat is getting in."

"But I want to know--" I began.

"Oh, bother your 'want-to-knows.' It's not against the law--just
outside it, you understand. I'll tell you more of it when we get to my
room. Give me that valise. Come along now." And as the boat entered the
slip we found ourselves at the front of the pressing crowd that is
always surging in and out of San Francisco by the gateway of the
Market-Street ferry.

As we pushed our way through the clamoring hack-drivers and hotel-
runners who blocked the entrance to the city, I was roused by a sudden
thrill of the instinct of danger that warns one when he meets the eye
of a snake. It was gone in an instant, but I had time to trace effect
to cause. The warning came this time from the eyes of a man, a lithe,
keen-faced man who flashed a look of triumphant malice on us as he
disappeared in the waiting-room of the ferry-shed. But the keen face,
and the basilisk glance were burned into my mind in that moment as
deeply as though I had known then what evil was behind them.

My companion swore softly to himself.
