Upon their knowledge and their fear of this, undoubtedly Calendar was reckoning: witness the barefaced effrontery with which he operated against them. His fear of the police might be genuine enough, but he was never for an instant disturbed by any doubt lest his daughter should turn against him. She would never dare that.

Before they left the house, while Dorothy was above stairs resuming her hat and coat, Kirkwood and Brentwick reconnoitered from the drawing-room windows, themselves screened from observation by the absence of light in the room behind.

Before the door a motor-car waited, engines humming impatiently, mechanician ready in his seat, an uncouth shape in goggles and leather garments that shone like oilskins under the street lights.

At one corner another and a smaller car stood in waiting, its lamps like baleful eyes glaring through the night.

In the shadows across the way, a lengthy shadow lurked: Stryker, beyond reasonable question. Otherwise the street was deserted. Not even that adventitous bobby of the early evening was now in evidence.

Dorothy presently joining them, Brentwick led the way to the door.

Wotton, apparently nerveless beneath his absolute immobility, let them out—and slammed the door behind them with such promptitude as to give cause for the suspicion that he was a fraud, a sham, beneath his icy exterior desperately afraid lest the house be stormed by the adventurers.

Kirkwood to the right, Brentwick to the left of Dorothy, the former carrying the treasure bag, they hastened down the walk and through the gate to the car.

The watcher across the way was moved to whistle shrilly; the other car lunged forward nervously.

Brentwick taking the front seat, beside the mechanician, left the tonneau to Kirkwood and Dorothy. As the American slammed the door, the car swept smoothly out into the middle of the way, while the pursuing car swerved in to the other curb, slowing down to let Stryker jump aboard.
