A Christmas mystery gift for adults who like their entertainment with a challenge. The Christmas Adult Mystery Gift Pack brings together two books from Harbor & Ink Press's Black Tie Murder Mystery puzzle series — a gift set made for mystery fans who want something memorable under the tree.

Each book in the Black Tie series drops you into a high-society crime scene: black-tie galas, candlelit ballrooms, and suspects who are far too polished to be innocent. You play detective — reading the room, weighing the clues, and naming the killer before the final reveal. The cases are designed for adults who enjoy a real puzzle, not just a quick read.

This adult puzzle book Christmas set is a strong pick for a partner, a mystery-loving parent, a sibling who's hard to buy for, or anyone who would rather unwrap something they'll actually use. Two books means two full evenings of proper puzzle-solving.

For adults 18+. Shipping: free on US orders over $30. Orders under $30 ship for $5. US orders only — we don't currently ship internationally.
