His death is ruled to be from natural causes. When Lady Tressilian is found brutally murdered in her bed, and her maid drugged a few days later, evidence points to Nevile Strange as the murderer as one of his golf clubs is found at the scene with his fingerprints on it. Her heirs are Nevile and Audrey. Nevile's quarrel with Lady Tressilian was also overheard.
