Mildred (Murder is Easy)

In the novel Murder is Easy, Aunt Mildred is the aunt of Luke Fitzwilliam. Lavinia Pinkerton whom he meets on the train to London reminds Luke of his aunt. To him there is something very cosy about old ladies like them. Luke thinks fondly of his aunt. Once she had allowed him to keep a grass snake as a pet. Another time she had lent him five pounds just when he needed it. His aunt was also "positively uncanny" about things. "What they fancy they see is very often right." Perhaps Lavinia, in believing that there had been murders in her village was like his aunt. To him they represent the "triumph of guesswork over logic".

Luke would later recall another incident about his aunt that would prove helpful. Once, Aunt Mildred had been talking about a "half-witted" person and then, for a moment, her own face had taken on an "imbecile, mindless express". Perhaps Lavinia Pinkerton, when speaking about the look she had seen on someone's face, had on her own face "reproduced the look that she saw ... the look of a murderer looking at his next victim...."
