“I happen to know her niece,” Mason said, “a Miss Virginia Trent. I’m going to advise her.”

“Well, we’ve tried to advise her and can’t locate her.” Sergeant Tremont told him. “There are a couple of angles on this. I think you’d better run down to headquarters and talk things over.”

There was a hint in the officer’s voice that the invitation might become more insistent if the occasion seemed to require, so Mason said casually, “Well, that’s not a bad idea. I’d like to investigate the circumstances and see if there’s anything I can do. Who hit her, Sergeant?”

“A man by the name of Diggers. He seems to be all broken up about it.”

“Are you holding him?”

“Temporarily. We’re going to let him go in a few minutes. Evidently she ran out in front of the automobile.”

“I’m just finishing dinner,” Mason told him. “I’ll get in my car and run down.”

“Better make it snappy,” Sergeant Tremont told him. “We want to ask you some questions about some diamonds.”

“Diamonds?” Mason echoed.

“Uh-huh,” Tremont said, and hung up.
