Dear Holmes

What's in the box: Each mystery arrives as a series of weekly clue letters in the mail, followed by a solution letter from Sherlock Holmes.

Dear Holmes sends Sherlock Holmes themed mysteries as paper letters, about one per week, so each case unfolds over roughly a month. Instead of a box of props, you get clue letters to read and compare, looking for lies and weak alibis until you can narrow the suspects. When you have a theory, you write it out, then check it against a solution letter from Holmes. The format suits people who prefer reading and deduction to hands on puzzles or escape room gadgets. The site recommends it for ages 14 and up and pitches it as a gift for bookworms and board game fans. It is sold as bundles: a starter pack of 2 mysteries for $49, 4 mysteries for $97, and 12 mysteries for $249. Each is listed with free First-Class postage and a choice of start month. Active members can also listen to narrated versions of their letters through a private podcast feed and hear recordings from past cases, a useful extra for audio fans. The slow pace is the main tradeoff. If you want to solve a whole case in one evening, waiting a week between letters may frustrate you. The paper only format also offers less variety than boxes with physical artifacts. For patient readers who enjoy getting real mail, it is a charming, low clutter option.
