Postscript to Poison

When Dr. Tom Faithful receives the third threatening, anonymous letter, he knows it is time to call the police. His wealthy patient, Cornelia Lackland, is recovering steadily from a serious illness, diligently cared for by him, her family members and her household staff. But something is amiss in Minsterbridge. Mrs. Lackland rules her house with an iron fist, keeping granddaughters Jenny and Carol as virtual prisoners and bullying her attendant Emily Bullen. Scornful and dismissive of everyone, she is planning to make one final change to her will. But, before she can meet her solicitor, Cornelia Lackland is dead, the apparent victim of a poisoner. Chief Inspector Dan Pardoe of Scotland Yard is called in to investigate an ever-growing list of suspects.
