Each claimed they were in the engine room maintaining turbines at the time of the murder. The engineer's clothes smelled of diesel. The doctor's clothes smelled of antiseptic. The First Mate's clothes smelled of ocean salt and fish. Which crew member lied about their location?
The First Mate
Engine rooms smell of diesel and machinery, not ocean salt and fish, proving the First Mate was up on deck, not in the engine room.
