I just finished reading this book and I liked it a lot. Part of the solution was so unexpected and the title of the book posed a very interesting problem! I found this to be very much in the vein of a Tommy and Tuppence book, and when I watched the movie from the 1980's and it had Francesca Annis and James Warwick as Frankie and Bobby, I had to keep checking myself. All in all, I thought the novel was very well written, and I thought AC connected seemingly unconnected events very intelligently. My only problem being that maybe there were too few characters who could have been the culprits. How would you rate Why Didn't They Ask Evans?
