I very much enjoyed this Christie novel the first time through, but on rereading in publication order, it wore a little thin. Bobby Jones & Frances Derwent are too much like pale imitations of Tommy & Tuppence in The Secret Adversary and Bundle Brent & Bill Eversleigh in The Seven Dials Mystery. The solution to the titular question is quite clever -- but it was so clever that I remembered it, further dampening my enjoyment in rereading. There also wasn't the same insight into character that Christie shows in other novels, particularly Poirot and Miss Marple novels. So all in all enjoyable, but not one of her greatest.
This book is also know as The Boomerang Clue......
Actually called the Boomerang Clue, but its the same book.
Definitely one of Christie's best.
Also published as "The Boomerang Clue."

An Excellent book that keeps you guessing to the very end. A must read!
