Anthony Holborne, Senior Master of St Cuthbert's School, is in line for promotion to the headship, but the day before the interview he is found dead by the matron. Is it suicide, or the work of a jealous rival? Francis Pilkington, another master at St Cuthbert's, takes on the case with the help of his new toy, a Commodore 64 computer. This book, the first in the Commodore 64 Mysteries series, is a traditional murder mystery rich in 80's nostalgia. This is a new, novel-length edition which contains several extra cases, a romantic subplot and five type-in programs.
