The 13th Hercule Poirot book, I quite enjoy this one. It really is quite ingenious in many ways. I like the idea of the murders - A name A surname in A town, followed by B name B surname in B town and so on. It would be quite interesting to have a serial killer working in that way (though X and Z may prove difficult, it'll have to be an international killer). Despite all appearances, however, this is not your ordinary serial killer. This is someone smart enough to hide a very personal, ordinary murder under the guise of a serial killer. I quite enjoyed the psychological assessment - exactly what one would expect from the time, and yet so amusing and quaint from a contemporary perspective. It does make one wonder what our 'cutting-edge' theories will appear to be in fifty or seventy-five years time. I particularly liked the murderer's attempt to frame an appropriately initialed man, though I found the characterisation of that man unbelievable.
Definitely an enjoyable holiday read.
