No Good Deed : Based on a book?????

Based on a book?????

I read the storyline and it looked familiar, especially the name of the murder and the other main cast. does anyone know if its based on a book or not and what the authors name is? its gonna drive me crazy because i am sure that i have read a book with the same storyline, its over 10 years since i read that book so maybe i am wrong, but i hate not knowing.
