"If them's the orders," he said at last, "there ain't no more to be said abaht it. I never thought to see meself walkin' in there, though, not of me own accord."

"They'll be civil enough," said Colin. "They only want to hear your story about getting me out of the cellar."

"I daresay you're right," admitted Joe doubtfully. "I ain't got nothin' special against the perlice; all I says is that the less you 'as to do with 'em the better." He paused. "Wot's the programme, guv'nor? Do I jest step up to the front door an' 'and in me card?"

"Doctor Ashton suggested that you should come round to the surgery. Then you can have some grub and drive up with us."

Joe shook his head. "Thankin' yer kindly, but if it's all the same I reckon I'll meet yer there. I gotter couple o' torfs comin' to the Palace for a lesson this mornin', an' it means a quid to me if I let 'em knock me abaht a bit."

"That's all right," said Colin, "as long as I can depend on you to keep the appointment."

"I'll be there, doctor," replied Joe. "I'll be there, honest to Gawd. You bring the young laidy along in the car, and yer'll find me sittin' on the Embankment waitin' for yer."

Satisfied with this assurance, Colin took his departure, and, retracing his steps to the end of the street, made his way back to Shadwell by the same route that he had come.

As he opened the door of the house he saw to his surprise that the note which he had left for Nancy was still lying on the hall table. Before he had time to realize anything further Mark suddenly appeared from the surgery.

"Hullo!" exclaimed Colin. "I made sure you'd be out on your round."
