Reno, Nevada, 1985. Americans and Soviets play a friendship chess match under the casino lights of the Golden Pawn, a hotel on Virginia Street, and morning after morning somebody in the hotel misses breakfast for good. The FBI sent Special Agent Ruth Calder to keep the peace. She is running out of peace.
Same rules as every Murder Mate: one white piece gives mate, the witnesses tell you which. At the Golden Pawn, the security agents are the white pawns, and one of them may have stepped off post.
Every case shows it with an arrow: a black pawn has just run two squares, straight past one of the agents.
For that first move only, the agent beside it may take en passant. Then the agent keeps moving like a pawn, and may even become a queen.
Sometimes the agent did it. Sometimes the agent only could have. In 9 of the 40 cases, the agent left the post for good.
Every square of the board belongs to a room of the Golden Pawn. Every white piece is a guest, always the same piece from one case to the next. You are the white king, Special Agent Calder, and you never move.


You only need to know how the pieces move. From Chief Inspector on, several suspects often break exactly one testimony each: only careful reasoning tells you which one is the lie. Each book stands alone.
Mate in one. Sometimes the agent beside the arrow did it.
