Sherlock is based on the legendary fictional detective Sherlock Holmes, created by Sir Arthur Conan Doyle.
It is Infocom's thirty-first game and is the first of two Infocom games developed by Challenge, Inc. using Infocom's development tools.
The year is 1887, and all of England is gearing up for the celebration of Queen Victoria's Golden Jubilee, marking her 50th year as monarch.
London, naturally, is especially frenzied.
Reading the paper one morning, Sherlock Holmes seizes upon one seemingly unimportant notice: the Tower of London has been closed for "reasons of security." The great detective is unsurprised when, moments later, he is asked to investigate the theft of the Crown Jewels.
The clues left behind, however, positively reek of a carefully laid trap; Sherlock decides that he must step aside and allow Dr.
Watson to pursue the thief instead.
But if the Jewels are not replaced within 48 hours, the British government will be forced to admit that their most prized possessions were stolen and suffer worldwide humiliation.
The player fills the role of Watson, travelling around London in Hansom cabs while attempting to recover the Crown Jewels while encountering many characters from Doyle's stories such as Mrs.
Hudson, Mycroft Holmes, and Wiggins of the Baker Street Irregulars.
About Commodore 64
Released in 1982, the Commodore 64 is the best-selling home computer model of all time, with an enormous software library spanning games, productivity tools, and everything in between. C64 game collecting centers on cassette tapes and floppy disks in their original packaging — physical media that's inherently fragile, so complete, working copies from the era are increasingly prized by retro computing collectors.
Gamevaro tracks Sherlock: The Riddle of the Crown Jewels for Commodore 64 with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Sherlock: The Riddle of the Crown Jewels to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This C64 release dates back to 1988.
