About
London, gaslight and fog. A man has vanished without a trace, a collector lies dead in a room locked from within. Two cases, one detective, and a keen mind that sees what others overlook: yours.
Sherlock Holmes: Secret Cases brings two complete detective stories to your pocket. Search atmospheric, hand-painted scenes for clues, decipher coded messages, reconstruct the sequence of events and confront the culprit with an airtight chain of evidence.
TWO FULL CASES
- The Shadow of Whitechapel — London, 1888. Edward has disappeared, leaving behind an enciphered letter. Follow the trail across five acts, from 221B Baker Street to the fog-bound Thames docks, and expose a shadowy figure from Moriarty's network.
- The Legacy of the Borgia Clock — Mayfair, 1889. A collector is poisoned in a locked room on the eve of an auction. Ten acts, a forged will, a hidden vault and a branching finale in which one false accusation lets the true murderer slip away.
WHAT AWAITS YOU
- Classic ciphers to break — Caesar and Vigenère, anagrams and number sequences
- Logic puzzles: reconstruct wills, disprove alibis, expose contradictory statements
- Interactive crime scenes with clues to discover
- A notebook that keeps track of every clue you gather
- A branching ending in the second case: think carefully before you accuse
- Atmospheric, painterly artwork and a period soundtrack of gaslit London
