Mr. Tertius glanced at Peggie, who was intently watching the caller.

“Ah!” he said, turning again to the driver, “you think you drove either Mr. Herapath or a gentleman of his appearance this morning. You did not know Mr. Herapath by sight, then?”

“No, sir. I’ve only just come into this part—came for the first time yesterday. But I’m as certain——”

“Just tell us all about it,” said Mr. Tertius, interrupting him. “Tell us in your own way. Everything, you know.”

“Ain’t so much to tell, sir,” responded the driver. “All the same, soon’s I’d seen this piece in the paper just now I said to myself, ‘I’d best go round to Portman Square and tell what I do know,’ I says. And it’s like this, sir—I come on this part yesterday—last night it was. My taxi belongs to a man as keeps half a dozen, and he put me on to night work, this end of Oxford Street. Well, it ’ud be just about a quarter to two this morning when a tall, well-built gentleman comes out of Orchard Street and made for my cab. I jumps down and opens the door for him. ‘You know St. Mary Abbot’s Church, Kensington?’ he says as he got in. ‘Drive me down there and pull up at the gate.’ So, of course, I ran him down, and there he got out, give me five bob, and off he went. That’s it, sir.”

“And when he got out, which way did he go?” asked Mr. Tertius.

“West, sir—along the High Street, past the Town Hall,” promptly answered the driver. “And there he crossed the road. I see him cross, because I stopped there a minute or two after he’d got out, tinkering at my engine.”

“Can you tell us what this gentleman was like in appearance?” asked Mr. Tertius.

“Well, sir, not so much as regards his face,” answered the driver. “I didn’t look at him, not particular, in that way—besides, he was wearing one of them overcoats with a big fur collar to it, and he’d the collar turned high up about his neck and cheeks, and his hat—one of them slouched, soft hats, like so many gentlemen wears nowadays sir—was well pulled down. But from what bit I see of him, sir, I should say he was a fresh-coloured gentleman.”

“Tall and well built, you say?” observed Mr. Tertius.
