7.Tape-Measure Murder is a short story by Agatha Christie.In the story,Miss Politt,the dressmaker,finds that Mrs.Spenlow is dead in her house in a small village called St Mary Mead.Everybody,including the police,thinks that Mr.Spenlow is the murderer (兇手) because he is so calm and quiet after discovering his wife's death.But after the police talk to Miss Marple,she finds out the real murderer.
The best part of the story is when Miss Marple explains how she solves the mystery (疑案) by noticing a tiny pin (別針) on a policeman's uniform.Her explanation is very clear and clever.Miss Marple is my favorite character in the story.I think she is very special because she is just an old lady but she is even smarter than the policemen.I never thought that an old lady could be the main character of a detective story!
Can you guess who the murderer is?Read the book to find out!You will enjoy the story very much because the ending is so surprising.
