The Reviews Are In...

Dear Holmes is a delight, with intriguing mysteries brought by characters that could have walked straight out of a real Sherlock Holmes story. My husband and I eagerly looked forward to every letter.
I got my first clue today. I've spent part of this evening trying to brute force decode the clue with some golang code, but no success. Such an interesting and entertaining gift.
All 10-year-old Gaelynn wanted to be was a detective, and now almost 30 years later her dream has come true! Thanks to @my_dear_holmes, Paul & my parents solve crimes every Friday night!
Well done on a fantastic mother's day gift. My mother and her friend are greatly enjoying their mystery subscriptions. I have to say, they're well written and a joy to read.
