a mystery to the end; and to Johnny Thompson it was to this time as great a mystery as in the beginning. * * * * * * * * * * * * * * * * Pant had left the circus train at Twenty-second Street. He had drawn his cap down to his dark goggles, and hurrying over to State Street, boarded a north-bound surface car. A half hour later he climbed the last of six flights of stairs, and turning a key in a dusty door, let himself into a room that overlooked the river at Wells Street. This room had been Johnny Thompson’s retreat in those stirring days told of in “Triple Spies.” Johnny had turned the key over to Pant before he left Russia.

Stake drivers, rope pullers, venders of peanuts and pop, mingle with the motley crowd of sharp-witted gentry who, like vultures following a victorious army, live in the wake of a prosperous circus. Later, all these would sleep, but for the moment, like owls and bats, they cling to the last bit of morning fog. It was down this much trodden “gold coast” at the back door of
