“Nothing!” he said to Duff. “No lead! Nothing new on the whole proposition. What we’ve got to do is go over it.”

“Go over it!” Duff groaned. “What do you think I’ve been doing since it started?”

Higgins ignored that. “I’ve got every man we have looking into everything they can think of! Mac — my chief — will be here soon. Reports will come in here. Now! Let’s go back to that day when you went upstairs to clean the rooms and you noticed Ellings’ closet was locked and you decided to pick the lock. You talk. I’ll ask questions. Start in!”

Duff stared at the other man, wondering if this was a useful effort or merely a kindly attempt to keep his mind from the final happening. It didn’t matter. Either way, it was better than just being silent and frantic.

Higgins and he covered every detail. McIntosh came and stayed a while, talked on the phone, issued orders, tried to comfort Mrs. Yates and Marian and Charles, and left.

Higgins and Duff talked on, without effect. Sometime after three in the morning, Higgins stopped alternately sitting and pacing. “Bogan,” he said, “I know you can’t sleep.

But I’ve got to. For me, it’s a job.”

“I understand that.”

“So I’m starting home. If you hit on anything else, let me know. If we can think of another thing for you to do, we’ll call you. This is rugged.”

Marian was asleep in a chair in the living room. Charles was asleep on the cot in his mother’s room. And Mrs. Yates didn’t say a word when he looked in. He went upstairs. After a while he lay down. Through his mind rushed the events he had just so painstakingly discussed with the FBI man. Little by little, in the dark, they ran less swiftly. And after a time, Duff sat up, rubbing his hair, putting his feet on the floor. He had told himself, with a different mental tone, that no feverish attempt such as he was making could accomplish a thing. He reminded himself that he was a scientist, capable of concentration, attention, analysis.
