About The Dead Letter Office
Aldermarsh, 1927. The Dead Letter Office receives the city's undeliverable mail — letters with smudged addresses, missing names, impossible destinations. You are Edie Marlowe, its newest clerk, and it is your job to send every letter home.
READ. DEDUCE. DELIVER.
Each case gives you a letter of about 200 words and an envelope carrying four clues: a postmark, an ink, a scent, a hand. Three residents of the city directory could have written it. Match the evidence, weigh the words, and choose — deliver the letter, or consign it to the Dead File.
A CITY THAT REMEMBERS
- 36 cases across five weeks, plus a Sunday Impossible every week
- 40 residents with portraits, trades, districts and tangled histories
- 8 interlocking story threads: the lighthouse keeper's unfinished letter, the forger, the two widows of Dockside, a marriage performed by post
- Letters you deliver change lives — follow-up notes tell you how
FEATURES
- Genuine deduction: every case is solvable from evidence alone
- Second Look hints when you're stuck (they cost stamps, not money)
- A five-week finale that names the city's secret — and a last letter addressed to you
- Cozy ink-and-paper presentation with an original period score
- Offline, single-player, no ads, no in-app purchases
The Dead File is the correct answer exactly twice. Choose carefully, clerk.
