Deadline

Deadline is a 1982 interactive fiction game from Infocom that puts you in the shoes of an unnamed police detective tasked with unraveling the suspicious death of wealthy industrialist Marshall Robner. Set in a sprawling Connecticut estate, the game challenges you to interview suspects, gather evidence, and piece together motives within a twelve‑hour in‑game deadline. The game was written by Marc Blank using Infocom's ZIL language, allowing it to run on platforms like the Apple II, Commodore 64, and modern Mac systems. With multiple possible endings, your deductions determine whether the case is a suicide or a cleverly concealed murder.
