The wild supposition that the Rajah himself was in the business was absurd. That idea might be dismissed on the spot. The more Field thought of it the more was he puzzled. He would take an early opportunity of seeing the Rajah.

"He's a quiet sort of man," the hotel manager explained. "I should fancy that he has an English mother, by the look of him. Anyway, he is English to all intents and purposes, having been educated at Eton and Oxford. He only took these rooms a few months ago; he was brought here after a bad illness, and when he went away he was carried to his carriage. But they say he's all right now. But, Mr. Inspector, you don't mean to say that you think that the Rajah——"

"Has any hand in this business? Of course I don't," Field said testily. "I'm just a little put out

this morning, so you must forgive my bad temper. The more one digs into the thing, the more black and misty it becomes. I think I'll go as far as the Yard and have a talk to one or two of our foreign men. Well, Saunders?"

"Well, I've done some good," Saunders said. "I have not found the cabman we want, but I've got on the track of another who can tell me something useful. He's a night man, and he is waiting down in the hall for you at this moment, sir."

"I think I'll go along, if you don't mind," Berrington suggested.

Field had no objection to make, and together the two descended to the hall. A little, apple-faced, shrivelled-looking man was waiting for them. There was no reason to ask his occupation—London cabman was written all over him in large letters.

"I can't tell you much, sir," he said. "It was just past two when I heard the whistle here. I was waiting with my cab at the corner of Shepherd Street. It's out of my line a bit, but I pulled up there in the hopes of getting a return fare. When I heard the whistle I came up with my cab, but I was just a shade too late. There was another cab before me, a black cab with a black horse, a rather swell affair. The driver was wearing a fur coat and a very shiny top hat. We had a few words, but the hotel porter told me to be off, and I went back to the stand where I stayed till just daylight. Nobody else left the hotel in a cab."

"This is important," Field muttered. "By the way, would you recognize the hall porter again? You would! Then come this way and we will see if you can."

But the cabman was quite sure that the damaged man lying on the bed at the top of the hotel was not the same one who had ordered him away a few hours before. He was quite sure because the lights in the hotel portico were still full on, and he had seen the hall porter's face quite distinctly.
