Lord Bellwater's Secret is a well-crafted single room mystery in a historical setting. The mood and style are nicely conveyed with excellent writing that sets the stage and provides the right motivation for the character.
Despite the seeming simplicity, I was definitely stumped on a couple of verb / parser issues that sent me to the built-in hints. The hints are well-done and thorough, but it made me feel like this was more of a "dig for clues" kind of puzzle than something that could be logically deduced like "An Act of Murder". Some of the puzzles have a laborious feel to them. But the story is good and the writing always pays back your efforts as the story proceeds.
There's quite a good drama that unfolds and the ending was quite exciting. It got my heart racing! I hope the author will continue with more mystery fiction.
