Puzzle Lady Cora Felton is hiding from her birthday by digging into a 20 year old murder. Why is someone interested in the case now? Is the real killer behind bars? The plot contains plenty of twists, but I felt the ending was overly convoluted. There was plenty of word play, which is why I read the series, so I loved that. Those who read for the cross word puzzles might be disappointed to learn they are unrelated to the mail plot. Personally, that didn't bother me.
