The premise is fascinating, but something about the way this was written made it hard for me to get into. Two gentleman meet on a train. One, Guy, latches on to the other and after a bit of conversation learns that he wants to divorce his wife and marry his mistress. Guy suggests that since he too has someone he would like to get rid of (his father) the perfect solution would be for each to murder the others nemesis--since each woud have no obvious motive there would be no way they would be suspected. The other gentleman passes this conversation off as Guy's drunken blather, but when Guy keeps contacting him after their chance meeting and then suddenly his wife dies he realizes that Guy really meant it--and that now ihe is in the worst trouble of his life. Guy's tremendous ability to sway this gentleman is brilliantly portrayed, but some of the detailed musings and descriptions of the characters inner angst was not the most thrilling thing to read. If you like wordy introspection combined with suspense, give it a try--otherwise skim over it and just read the action scenes or watch the movie.
