Mrs. Ingelthorp, the elderly and wealthy owner of Styles Court is found dead in her own bedroom, which is locked from the<br/>inside. The cause of death has all the appearances of strychnine poisining. Who could possibly have wanted her dead? Or<br/>perhaps the better question... who wouldn’t?<br/>There is no shortage of suspects in this classic “locked-room” mystery, but no proof to tie any of them to the murder... until Poirot arrives.
