Mrs Blade

In the short story Tape-Measure Murder, Mrs Blade is the postmistress in St. Mary Mead. The post-office/shop which she managed was one of only two places in St. Mary Mead with a public telephone. In discussing how a hoax call could have been made to Miss Marple, both Inspector Slack and Colonel Melchett dismiss the idea that it could have been done from the post-office because Mrs Blade would have seen everybody who came in. They did not know that at 2.30 p.m., when the bus from Much Benham arrived outside, Mrs Blade would rush out to meet the bus.
