that everyone's a suspect.
I thoroughly enjoyed this one. The victim, Mrs. Boynton, is a masterful character study of a truly awful person. Hercule Poirot works his psychological magic even though every single character in this book - save himself - had a motive for murder. The exotic Jerusalem setting is fun, and Sarah King is one of my favorite secondary characters so far.
The epilogue was a lot of fun, as well. Sometimes the world really is a better place with someone NOT in it.
