WATCHFUL AT NIGHT

Army medic backdrop and detail for the solo operations of war seasoned, toughened Sgt. Clark -- whose buddy is shot -- deliberately -- on the rifle range and who loses a second man in his outfit in an intentionally bungled blood transfusion. Clark, with little to go on save an address book, gets a lead to a girl, a Harvard professor of the wave of the future, and a fascist minded organization, headquarters Boston. Medical minutiae add fresh interest to a familiar murder-espionage pattern.
