Query: A cruel book!!!!

This is a well written book which explores the mind of a tormented man who has just lost his wife .BR> I really enjoyed this book until about half way through when animal cruelty invaded it. It was disturbing and shocking to read about cruel experimentation on dogs.The story had its merits and there was no need for the author to destroy it with animal cruelty. WHY WOULD SHE GO THERE???This book is not for people who love dogs or for that matter anyone who has a heart.
