"Thanks!" With a flash-like movement Caw nipped away the notes. "You've got to pay something!"

Springing round behind Bullard, he shoved the cold steel into the nape of his neck. "March! and you, too, Mr. Lancaster. Take your friend's hat!"

Ignoring his colleague's gaze, which had moved suggestively from himself to the fire-irons, Lancaster obeyed and made for the door.

"You'll be devilish sorry," began Bullard, beside himself—

"Another word, and you'll lose one ear—to begin with. March!"

Sullenly Bullard moved forward. Not until he was in the garden did he attempt speech, and then his voice was thick, though fairly under control.

"Well, my man," he said, "you've got yourself into a nasty hole. Robbery, with a revolver in your hand, is rather seriously regarded by the law. But as you have acted on impulse and misapprehension, I am disposed to give you a chance. Restore those notes—"

"Looks like being a wet night," said Caw, and shut the outer door.

When he had made it fast he switched off the lights in the hall and went upstairs. In his master's room he wavered, and his eyes rested longingly on the decanters, for he was feeling the reaction. But he was a good servant still, and it would be "hardly the thing" to take a dram there and then. Yet he forgot the conventions of service when, a moment later, he sank upon a chair and bowed his head on his master's table, sick at heart, sore in pride. He had been so easily tricked! And yet what difference would it have made if they had walked out of the room with the Green Box in their possession? But he was very sure they would not have dared so greatly, unless, perhaps, with force of arms—in which case, despite all promises, he knew he would have resisted. It never occurred to Caw to doubt his master's sanity, but now he began to wonder what had possessed Mr. Craig in regard to the Green Box. Six hundred thousand pounds! He seemed to see his master seated at the table, calmly naming the stupendous sum—and in the same instant he realised that he himself was sitting in his master's place. He sprang up, and almost fell over the open drawer. He stooped to close it, straightened up with an exclamation, only to drop to his knees, staring, staring at—the Green Box! Suddenly he gave a short chuckle, rose, and made for the door in the back wall.

Ere he reached it, it opened. A girl came in.
