Montague Island Mysteries is a collection of logic puzzles thematically presented as a series of visits to a remote island. Your hosts, as well as the fellow guests, are fellow puzzle enthusiasts who gather at the island for twelve weekend visits, during each of which a mystery puzzle is presented along with several ancillary ones. The theme is used nicely as the reader will be determining things like the guests’ backgrounds, what room everyone’s in, further details about the island, etc.
Of course with a book like this the quality of the puzzles is paramount, and in this respect MIM is spot on. Classic grid based logic puzzles are mixed in with a nice variety of spacial reasoning, unique visualizations, etc. The mystery puzzles feature a mechanic I particularly adore that involves the “culprit” secretly being among the guests and giving statements that might or might not be true. It provides a nice twist and was used with just about the right frequency (although a few more in this style would have been great).
There are a couple of minor missteps. A few puzzles are based on every attendee, including the player, being given two cards or something similar with the instructions “don’t show them to anyone else” and the solution based on determining who has what. But the reader’s own cards are not revealed, their persona just presents statements that may or may not be true like everyone else. This does not affect solving the puzzle, but is thematically awkward given the presentation and a bit of a missed opportunity as well.
Some of the puzzles were too long and/or required too much brute force for me, although given the scope and variation of what’s presented a few puzzles not being to my particular tastes is no big deal. One pushed mathematical logic versus linguistic logic a bit far for my liking, but again that’s personal preference.
Overall Montague Island Mysteries is a wonderful collection of puzzles with a solid connecting theme. I enjoyed this book quite a bit and look forward to checking out the sequel.
