CosyKiller Murder Mystery

CosyKiller is a slow-burn murder mystery for armchair sleuths, told across twelve monthly boxes. You play an heir who has inherited a cold case, and each box adds new evidence in the form of vintage-style memorabilia: diaries, letters, telegrams, tickets, newspaper clippings, portraits, government documents and ciphers, with a few false leads mixed in to throw you off. Every subscriber starts with Box 1, a diary that sets the scene, whenever they join, and the current story is An Inheritance of Murder, built around letters from 1934 and a missing girl. Each box arrives with a letter personalized to the recipient, which makes it work as a gift. It is recommended for teens and up, and you can play alone or with a small detective team. Internet access is not required, though hints are available through private Facebook groups and a secret website. CosyKiller ships from the United Kingdom, and new orders go out within three business days. UK orders travel by Royal Mail second class, while US and Canadian orders use international standard shipping to clear customs easily, with boxes expected within 21 working days. The listing does not state the shipping cost. Pay monthly or prepay three, six or twelve months. It suits mystery readers and puzzle fans who enjoy a story that unfolds slowly over a year.
