This author is a must for all mystery readers. Everytime I read one of Ms. Spindler's books, I feel it is her best. After reading "Cause for Alarm", I know this is her best so far. I couldn't put this book down until John got what was coming to him. What a wonderful book! I can't wait until her next novel.
