Sandra Sharkey is a British text adventure author and writer. She is best known for being one of the original editors of Adventure Probe fanzine and for her IF work such as The Case of the Mixed-Up Shymer and Scapeghost.
Together with Pat Winstanley, Sandra set up and edited the initial issues of the long-running Adventure Probe fanzine in June 1986. She continued editing the magazine until Mandy Rodrigues took the reigns in 1988.
Sandra's well-received work, The Case of the Mixed-Up Shymer was originally written using the GAC for the Amstrad CPC. There were later ports of the game for C64 (by Mandy Rodrigues), ZX Spectrum, Amiga, and Atari ST.
The Atari ST version of the game formed part of Incentive's official STAC authoring system bundle. Sandra was heavily involved in the testing of the product. The graphics for the Atari ST version were by Dicon Peeke.
Sandra also spent some time writing as The Sorceress in the adventure column of Sinclair User; a role that was also occupied at one point by her friend, and fellow Scapeghost writer, Peter Gerrard.
