I have just watched this adaptation of the Miss Marple book "Nemesis" and am rather lost as to why this telemovie should be called the same.

The only characters in common with the book are Miss Marple (played all wrong by McEwan - again), Raymond West and Jason Rafiel. All of the other characters did not appear in the book. Again, as this series has done so may times in the past, the murderer has been changed and the entire plot of the novel reworked so that even those murdered during the course of the book are changed. The bus driver is portrayed as a sort of maniacal jailer with a mountain climbing fixation.

If you want a proper interpretation of the novel, go for the Joan Hickson version - this one is just plain odd.
