Then he had asked for the Thames police, pulling the door tighter and so exasperating the waiting gentleman.

"Has 276 River Walk a motorboat, do you know?"

There was a consultation at the other end.

Yes, 276 had a boat. Yes, very fast. Seagoing? Oh, yes, if necessary. Used it for fowling along the Essex flats, they thought. Used for navigation of the lower river, anyhow? Oh, yes.

Grant asked if they would have a boat ready for him in about an hour and a half, by which time he'd be in town, he hoped. He'd take it as a great favor.

Certainly, they would.

Grant telephoned to Barker — at which point the patent leather gentleman gave it up — and asked that if Williams was back in town within the next ninety minutes he should meet Grant at Westminster Pier. If Williams was not back in time, then Sanger.

Grant took full advantage of the lunchtime lull in traffic, and in unrestricted areas excelled himself in the gentle art of speed with safety. He found Williams waiting for him, a little breathless, since he had that moment arrived from the Yard and sent the disappointed Sanger back. Williams had no intention of being out of anything, if he could help it. And the Superintendent had said that something exciting was due to break.

"Well, was the Reverend Father shocked?" Grant asked.

"Not as shocked as Brother Aloysius. He didn't for a moment imagine we'd got anything on him. By the way he behaved, I should think some other police forces must be anxious to catch up with him."
