Letters Under Wax

In the spring of 1923, Lady Cordelia Ashwell was found dead at her writing desk. The letters she had been keeping for the last year of her life were never sent and never read. You are her only heir. The bureau is yours now.
Letters Under Wax is a quiet, ten-letter mystery told entirely through correspondence. Each envelope arrives sealed her way — a candle to the wax, a cipher wheel, a forgotten flower, a tune held in memory, a page reversed in a looking-glass. No two locks are the same.
When the seal yields, the letter unfolds in her own hand. You read what she wrote, take in what she left unsaid, and choose how to write back. Answer in kindness, in cunning, or in cold defiance. Every reply changes who writes next, and what the next envelope holds.
Along the way you keep what she gave you. A pressed violet between the pages. A brass key engraved with a single number. An open locket bearing a date. A train ticket stub from a station no longer in service. Some envelopes will not open without what an earlier one left behind.
There are ten letters, five keepsakes, and four endings. The bureau remembers which ones you have found. Return as often as you wish to walk into the rooms you have not yet walked into.
One last touch — a hand-built looking-glass that frames the lens of your phone in antique brass, so you may keep a quiet memento of where you sat while reading her.
A short, hand-written story. About thirty minutes a sitting. Best read once a night.
