“Yes, it was interesting—very. I went, as I told you I should, to try and get hold of a clue.”

She turned to him quickly:

“Oh! Did you find out anything?”

“Very little so far. I’ll tell you all about it when we get in. I should have told you before, of course, if you hadn’t been away.”

“There’s a tram stopping,” she said inconsequently, and made for it. “Which way are you going?”

“To take you home, of course.”

“I’m not going home, but to Grace at Buckingham Gate. She’s there now.”

He nodded; it was impossible to talk in the noisy and crowded tram.

“We’ll take a taxi from here,” he suggested meekly when they alighted at the terminus opposite the station.
