He admitted that he would be leaving Lord Thrubb's employ to look after Lady Edith in her new house. Bufton explained a £25,000 deposit in his bank account as an inheritance from an aunt and this was investigated and found to be true.

Mrs Grice:- The housekeeper and cook accused of listening at Lord Thrubb's door. She claimed to be picking up investment tips but she was under investigation for the theft of items of silverware from The Grange. Rat poison found in Mrs Grice's larder was tested and found to be a different substance to the chemical that killed Lord Thrubb.

Denver Colorado:- A business partner of Lord Thrubb visiting for a meeting about a business venture that Lord Thrubb was investing in. In the course of the investigation it was discovered that Colorado had a significant holding in a chemical company that produced potassium cyanide. A rumour that Colorado Mining had made a huge gold discovery was found to be false.

Hubert Thrubb:- Lord Thrubb's nephew. Lord Thrubb has recently changed his will to make Hubert the principal beneficiary of his business interests. Investigators established that Hubert was being threatened over gambling debts of more than £100,000. He had approached his uncle and asked for a loan to cover his embarrassment. Bufton tells the Police that Lord Thrubb was severely disappointed in his nephew's gambling and was going to tell him that he was reconsidering his inheritance.
