My only answer was my own voice reverberating in a rolling echo from the cliffs around me.
It was the sight of that Alpine-stock which turned me cold and sick. He had not gone to Rosenlaui, then. He had remained on that three-foot path, with sheer wall on one side and sheer drop on the other, until his enemy had overtaken him. The young Swiss had gone too.

I stood for a minute or two to collect myself, for I was dazed with the horror of the thing. Then I began to think of Holmes's own methods and to try to practise them in reading this tragedy.

As I took it up a small square of paper upon which it
