Up to date I had led the normal life of a super-civilized city dweller, but within a fortnight I was to shoot a man down and count it just part of the day's work. None of us knows how strong the savage is in us until we are brought up against life in the raw.

My trailers followed me about next day as usual, but I chuckled whenever I saw them. For we were doing a little sleuthing ourselves. I borrowed Jimmie from the firm and the little gamin kept tab on Bothwell.

The captain did not leave his room until nearly midday, but as soon as he had turned the corner next to his hotel, the Argonaut, on the way to his breakfast-lunch, Jimmie dodged in at the side entrance, slipped up the stairs and along a corridor, up a second and a third flight by the back way, down another passage, and stopped at a room numbered 417.

With him he had a great bunch of keys similar to those used in that hotel. One after another he tried these, stopping whenever he heard approaching footsteps to hide the keys under his coat. Several persons passed, but found nothing unusual in the sight of a boy knocking innocently on a door.

At last Jimmie found a key which turned in the socket. That was all he wanted. Relocking the door he went down the stairs to the street, his fingers tightly clenched around the key that fitted. Nor did he take the little closed fist out of his coat pocket until he and I were alone together in my office, from whence he departed two dollars richer than he had entered.

Jimmie having been retired from duty, Blythe took his place in watching Bothwell. He engaged a room on the fourth floor of the Argonaut, from which he was able to observe the coming and going of the enemy.

My work at the office finished, I took a car for the Graymount, followed as usual by one of the detectives that for days had dogged me. My attendant on this occasion was a shrimp of a man with a very wrinkled face and a shock of red hair. Some imp of deviltry in me moved me to change my seat for one beside his.

"A pleasant day," I suggested to open the conversation.

He agreed that it was.

"I suppose your kind of work is always more cheerful in good weather," I went on.
