A master of subterfuge Winston Greeves was adept at working undercover within various organisations. He said his most enjoyable undercover experience was masquerading as a crime boss in a prison located on the Yorkshire Moors. It was during this assignment he foiled a fellow crime lords Italian gold robbery attempt by recommending an incompetent driver (See The Bridger File).
His hobbies included being an amateur meteorologist (he enjoyed being able to inform other Society members when winter was coming) and keeping birds. It was this hobby that led to Winston recently retiring from Society business to spend more time looking after his two ravens Samson and Delilah.
