Bobby was grateful for Graham's presence. It was like the man to assume his responsibilities, to sacrifice himself in his service. He straightened. He must meet these two. Through his own wretched appearance and position he must develop for Katherine more clearly than ever Graham's superiority. He stepped out, calling softly:
"Katherine!"
She started. She turned in his direction and came swiftly toward him. She spread her hands.
"Bobby! Bobby! Where have you been?"
There were tears in her eyes. They were like tears that have been too long coming. He took her hands. Her fingers were cold. They twitched in his.
"Look at me, Katherine," he said hoarsely. "I'm sorry."
Graham came up. He spoke with apparent difficulty.
"You've not been home. Then what happened last night? Quick! Tell us what you did—everything."
"I've seen the detective," he answered. "He's told you, too? Be careful.
I think he's back there, watching and listening."
Katherine freed her hands. The tears had dried. She shook a little.
