I didn't know this was a book in a series of Asey Mayo Cape Cod Mysteries, but it didn't matter that it was #20. You didn't need to read the others first to understand the story line. I was intrigued that it was written in 1943 - which is why I bought it. I wanted to compare the writings of that era to todays.
I enjoyed the writing, the setting (war rations and such) and the characters. However, it was a bit slow and added way too many twists. I should have written down the characters and their relationship to the others as I put it down for a few days, and when I picked it up again, I had forgotten who was who. Yes, I am 70 y/o, but can usually remember stuff!
I'm not quite sure what the meaning of the books were (and that was a big issue) being thrown in the water, scattered on the winding road, the type of bindings, etc. I must have missed something along the way. All in all, it was an interesting mystery with a surprise conclusion, but it could have been shorter - and I should have read it concurrently and not wait a week in between readings!
