Markham grunted but did not answer. He began pacing up and down agitatedly, keeping his eyes expectantly on the main entrance. Vance sought a comfortable chair, and settled himself in it with placid unconcern.

Ten minutes later Heath and Snitkin arrived. Markham at once led them into an alcove and briefly explained his reason for summoning them.

“Spotswoode’s up-stairs now,” he said. “I want the arrest made as quietly as possible.”

“Spotswoode!” Heath repeated the name in astonishment. “I don’t see——”

“You don’t have to see—yet,” Markham cut in sharply. “I’m taking all responsibility for the arrest. And you’re getting the credit—if you want it. That suit you?”

Heath shrugged his shoulders.

“It’s all right with me . . . anything you say, sir.” He shook his head uncomprehendingly. “But what about Jessup?”

“We’ll keep him locked up. Material witness.”

We ascended in the elevator and emerged at the third floor. Spotswoode’s rooms were at the end of the hall, facing the Square. Markham, his face set grimly, led the way.

In answer to his knock Spotswoode opened the door and, greeting us pleasantly, stepped aside for us to enter.
