Hello all,
Many years ago, in about 1980, I read a novel that I would like to read again. The problem, of course, is that I can remember neither the title nor the author.
The protagonist is an actuary, married to a shrewish wife. One day, he formulates a plan to murder said wife, using his skills as an actuary. He researches accidents in the home and decides to provoke an accident wherein his wife will slip and fall in the bathtub.
His research uncovers that a particular brand of bubble bath liquid is especially slippery, and is involved in a number of home accidents. He further discovers that a specific model of bathtub grab bar is likely to work loose and detach from the wall.
Combining these items, he engineers a situation where his wife, after a stressful day at work, is taking a relaxing bubble bath. He leaves the house, on the pretext of taking a walk. After an appropriate period of time, when he is sure that his wife is suitably ensconced in the bathtub, he heads to a pay phone and calls home. Timing the call precisely, he hangs up just before his wife would be answering the phone. Waiting until she is certainly back in the bathtub, he repeats the process. After several more iterations, he returns home to find his wife dead, with a broken neck. Needless to say, this is a black comedy.
I have tried as many different combinations of search terms as I could imagine, but have had no luck in identifying the book. I realise it might well be out of print by now, but this has become a quest, if you know what I mean.
Can anyone help me find this book? Regardless of the success of the endeavour, thank you for any and all help.
