To me it was apparent that Bob Brackenbury was very popular with a certain set at the Motor Club, at the Automobile Club, and at other resorts.

My duties were not at all arduous, and such a thoroughgoing sportsman was my master that he treated me almost as an equal. When out in the country he compelled me to have lunch at his table "for company," he said. My people, I told him, had been wealthy before the South African War, but had been ruined by it, and though I had been at Rugby and had done one year at Balliol College, Oxford, I hid the fact now that I was compelled to earn my living as a mere chauffeur. He had no idea that I was a barrister, with chambers in New Stone Buildings.

One morning after breakfast Mr. Brackenbury called me into the little dining-room, wherein stood his capacious roll-top desk against the wall, with the telephone upon it, and inviting me to a seat opposite the fireplace, said in a voice which betrayed just the faintest accent:

"Nye, I want to speak confidentially to you for a few minutes. You recollect that the day before yesterday when down at Windsor I was speaking with a police-inspector in uniform, who called at the hotel to see me, eh?"

"Yes. He looked round the car and spoke to me. I thought he'd come to take our name for exceeding the limit on the Staines road."

"You'd remember him again if you saw him?"

"Certainly," was my prompt reply.

"Well, don't forget him," he urged, "because you may, before long, be required to meet him. And if you should chance to mistake the man, a very serious contretemps would ensue."

"I'd recognise him again among a thousand!" I declared.

"Good. Now listen attentively to me for a few minutes," he said, lighting a fresh cigarette and fixing his dark, penetrating eyes upon mine. "I and my friend Shand have a very difficult task. A certain Colonel von Rausch, of the German Intelligence Department, is, we have discovered, in England on a secret mission. It is suspected that he is here controlling a number of spies who had been engaged in staff-rides in the eastern counties, and to receive their reports. My object is to learn the truth, and it can only be done by great tact and caution. I tell you this so that any orders I give you may not surprise you. Obey, and do not seek motive. Am I clear?"
