Deadline (1982)

Twelve fictional hours turn an apparently settled death into a demanding exercise in observation. The Robner household carries on while you search, arrange analysis and compare what people say with where they actually go. An important opportunity can pass while you pursue a different lead, so an exploratory run and a notebook of times are useful. Read the supplied case documents before starting, and keep early SAVE files for RESTORE. There is room to think at each prompt, but little reassurance that you have already missed something essential.
