Under normal circumstances Anderson would have been the stronger and quicker, but the Doctor fought with an added strength of despair and his initial leap had pinioned the detective's arms behind him.

Now the detective shook one hand free and snatched at the revolver--in vain--for the Doctor, with a groan of desperation, struck at his hand as its fingers were about to close on the smooth butt and the revolver skidded from the table to the floor.

With a sudden terrible movement he pinioned both the detective's arms behind him again and reached for the telephone.

Its heavy base descended on the back of the detective's head with stunning force.

The next moment the battle was ended and the Doctor, panting with exhaustion, held the limp form of an unconscious man in his arms.
He lowered the detective to the floor and straightened up again, listening tensely.
