It was originally designed, and programmed by Lee Kristofferson (born John Wagstaff) in assembly language for the Commodore 64.

Versions were later ported to the ZX Spectrum and BBC Micro, both written in BASIC.

Written to the main character from the perspective of a friend "Mike", it outlines how (a presumed mutual friend) Richard's company, Comdata, has had $1.5 million stolen by a rival company named Realco.

The letter provides a single phone number and entry code, part of the game's simulation of dialing into databases and bulletin boards.

The player has to figure out how to get into the proper database to take back the cash.
