James Frazer sought a divorce, but his wife steadfastly refused to grant it. Simultaneously, she was pilfering the blueprints to his latest invention, a calculated move to ensnare her engineer lover. Seeking respite, Frazer departed for three months, intending to regain his composure. Yet, upon his return, he discovered his wife murdered in his office—and he alone possessed the key to the intricate, burglar-proof lock he had designed.
