“It is a cab,” said Sherlaw.
They heard it draw up before the front door, and then there came a pause.
“Who the deuce can it be?” muttered Escott.
In a few minutes there came a knock at the door, and a servant entered.
“A new case, sir. Want’s to see Dr Congleton particular.”
“A man or a woman?”
“Man, sir.”
“All right,” growled Sherlaw. “I’ll come, confound him.”
“Bad luck, old man,” laughed Escott. “I’ll wait here in case by any chance you want me.”
