The patient nodded.

“There was an electric brougham,” he continued, “drawn up alongside the taxi. While we were there, waiting, I saw a chap get out, speak to some one through the window of the taxi, open the door, and step in. When we moved on, he stayed in the taxi. Dark, slim chap he was,” the patient continued, “a regular howling swell,—silk hat, white muffler, white kid gloves,—all the rest of it.”

“And afterwards?” the Inspector asked.

“I kept behind the taxi,” the youth continued. “We got blocked again at Hyde Park Corner. I saw him step out of the taxi and disappear amongst the vehicles. A moment or two later, I passed the taxi and looked in—saw something had happened—the fellow was lying side-ways. It gave me a bit of a start. I skidded, and over I went. Sort of had an idea that every one in the world had started shouting to me, and felt that I was half underneath an omnibus. Woke up to find myself here.”

“Should you know the man again?” the Inspector asked. “I mean the man whom you saw enter and leave the taxi?”

“I think so—pretty sure!”

The nurse came up, shaking her head. Inspector Jacks rose from his seat.

“Right, nurse,” he said. “I’m off. Take care of our young friend. He is going to be very useful to us as soon as he can use his feet and get about. I’ll come and sit with you for half an hour next visiting day, if I may?” he added, turning to the patient.

“Glad to see you,” the youth answered. “My people live down in the country, and I haven’t many pals.”

Inspector Jacks left the hospital thoughtfully. The smell of anaesthetics somehow reminded him of the library in the house at the corner of St. James’ Square. It was not altogether by chance, perhaps, that he found himself walking in that direction. He was in Pall Mall, in fact, before he realized where he was, and at the corner of St. James’ Square and Pall Mall he came face to face with Prince Maiyo, walking slowly westwards.
