Strange Loyalties

A woman driver, of course!" had been Dr. Richard Guyse's impatient inward comment as he braked and swerved to avoid a collision with the open car door of the unknown but attractive young girl.

He could always switch his concentration to the important details of his busy doctor's life - yesterday's operation, today's X-ray, tomorrow's problematical new case - to the exclusion of everything else. Doctor Guyse did not know it then, but his meeting with Lysbet Marlowe was the beginning of a strange disturbance in his powers of concentration.
