The Case of Cabin Seven
Reedmere Holiday Camp, August 1932. A real mystery, just the right size for reading aloud. Age-appropriate stakes, fair clues, and an ending that still waits for letter 6. Warm, never babyish; curious, never scary.
- Ages ~9–14
- No murder · no child harmed
- One-time purchase
Cabin Seven’s shoes appear in a ring on the jetty at dawn.
Family promise: No graphic content, no horror framing, no children-in-peril tropes. Mysteries focus on missing objects, puzzling messages, and community secrets a family can discuss together. Real logic. Right-sized stakes.
Counsellor Bess Marlowe needs an outside mind after Cabin Seven’s shoes appear in a ring on the jetty at dawn, though every child answers roll call. Age ~9–14; no murder; no child harmed. One early clue: the Parents’ Boat Fund tin weight that no longer matches the treasurer’s signed page.
Digital envelopes. One complete case.
Each delivery is a letter (~2 pages) plus printable extras. Choose the $27 drip (one letter every 5 days over about 26 days) or $37 unlock-all (all six at once). Two-Lock ending: letters 1–5 plant who and how; the decisive why and final proof open in letter 6.
Shorter letters, clearer artifacts, questions kids can answer. Grown-ups still enjoy the craft.

FAQ
Is this a subscription or physical mail?
No. Both $27 and $37 are one-time purchases of one complete digital case. Letters arrive by email. Print what you want; keep the rest on screen. Not a recurring subscription and not postal mail.
What if I stop reading early?
You keep every letter already delivered. The drip is not a cancelable subscription that stops billing; you already paid once. Lock Two (the decisive why and final proof) is in letter 6, so finishing matters for the ending, not because billing continues.
How does checkout work?
Checkout opens WarriorPlus in a new tab. Vendor name appears as Ry04Mac. Choose Buy drip · $27 or Unlock all · $37. 14-day money-back guarantee. Delivery by email from hello@monthlycasefile.com.
Does the free case spoil this one?
No. The free complete three-letter mystery (The Silver Bloom Cup) is a separate mini-case and does not spoil any paid case.
