Mr Grove

Mr Grove is a non-canonical character who was created for the film adaptation of Yellow Iris in Series 5 of ITV's Agatha Christie's Poirot. He is the former solicitor of Lord Wetherby, the father of Iris Russell and Pauline Wetherby. Poirot sent Hastings to meet Mr Grove at the town of Reepham in Norfolk "to find a motive for murder". At the grave of Iris Russell, Mr Grove told Hastings about some of the background Hastings needed. The wealthy Lord Wetherby had died and had left all his fortune to Iris. Iris had herself made a will. Since her husband Barton Russell was already wealthy in his own right, Iris left her estate to her sister Pauline to be held in trust until she turned 21. Barton was made Pauline's guardian until that time. However, to Hasting's surprise, Barton would not stand to inherit if Pauline were to die. Pauline had herself made a will. Mr Grove could not disclose the terms of her will but he said that he feels afraid for her. When she came to sign the will, she was accompanied by a young man (presumably her fiance). "Make of that what you will," Mr Grove tells Hastings.
