“Who rooms in Number 7?” it demanded.

There was a moment of silence during which the fellows around Alf Loring observed him with startled gaze and showed a disposition to remove themselves from close proximity.

“I do, sir,” answered Loring.

The Doctor’s gaze wandered over the group and found him. There was a flush on his cheeks, and the Doctor seized upon it as an evidence of guilt.

“Indeed?” he asked complacently. “And who else, pray?”

“Tom Dyer, sir.”

“I will see you and Dyer in the Office after breakfast, if you please,” said the Doctor.
