Parker

Parker opened the door for Dr. Sheppard on the night of the murder, brought in the evening post, and later telephoned the doctor to report his employer's death. When Sheppard arrived, Parker first denied making that call. He helped break down the study door and identified the wound as a stabbing from behind. His behavior was suspicious from the start; he had looked embarrassed near the study door as if eavesdropping, and he told a palpable untruth about hearing the bell. After the police arrived, he conveyed Flora Ackroyd's message that her uncle was not to be disturbed, yet he became suspiciously flustered when the inspector questioned him about whether he had attempted to do so anyway. Under further questioning by Inspector Davis, Parker panicked and blurted out a confused tale of blackmail, which solidified the inspector's suspicion of him.
