The Perfect Gift For Agatha Christie Superfans.

We all have that friend or relative who loves Agatha Christie.

They’ve read every Hercule Poirot novel (twice) and dressed up as Miss Marple or Hastings for several Halloweens.

Dear Holmes is the twist-filled mystery gift built just for them.

The Dear Holmes Experience

Take on a new mystery every month. Review the evidence, separate truth from mistruth, and solve the case.

Each week, you’ll receive a letter with new clues to help you crack the case. Then, Sherlock Holmes will write you with his solution.

Prove your deductive mettle by competing with detectives around the world for the coveted Featured Detective prize.

Your clue letters will arrive by snail mail. Prefer to listen to your letters? You’ll have access to our members-only podcast.

Crack secret codes. Build a “murder board” to keep track of suspects, clues, and alibis as they arrive.

With Dear Holmes, you can finally step into the shoes of your favorite literary detectives and use your “little grey cells”.

Below are just a few of the whiteboards, diagrams, and visual aids our members have made to solve past mysteries.
