When I first came to London I had bought a car and amused myself with running about the south of England, so I knew something of the geography. I took Sir Walter to town by the Bath Road and made good going. It was a soft breathless June morning, with a promise of sultriness later, but it was delicious enough swinging through the little towns with their freshly watered streets, and past the summer gardens of the Thames valley. I landed Sir Walter at his house in Queen Anne’s Gate punctually by half-past eleven. The butler was coming up by train with the luggage.

The first thing he did was to take me round to Scotland Yard. There we saw a prim gentleman, with a clean-shaven, lawyer’s face.

“I’ve brought you the Portland Place murderer,” was Sir Walter’s introduction.

The reply was a wry smile. “It would have been a welcome present, Bullivant. This, I presume, is Mr. Richard Hannay, who for some days greatly interested my department.”

“ Mr. Hannay will interest it again. He has much to tell you, but not today. For certain grave reasons his tale must wait for four hours. Then, I can promise you, you will be entertained and possibly edified. I want you to assure Mr. Hannay that he will suffer no further inconvenience.”

This assurance was promptly given. “You can take up your life where you left off,” I was told. “Your flat, which probably you no longer wish to occupy, is waiting for you, and your man is still there. As you were never publicly accused, we considered that there was no need of a public exculpation. But on that, of course, you must please yourself.”

“We may want your assistance later on, MacGillivray,” Sir Walter said as we left.

Then he turned me loose.
