For thirty years, Denis was partner in a small London design consultancy specialising in technical and marketing material for the insurance, pharmaceutical and shipping industries. During that time, he was not afraid of taking a red pen to the grammatical mistakes and stylistic inconsistencies in text supplied by clients. Now retired, he divides his time between London, where he is a father and grandfather, and Tallinn, where he is a house-husband. Apart from reading, going to galleries and concerts, he is enthusiastic about golf but finds it very challenging – rather like learning Estonian. He also spends a lot of time in shopping centres looking for exciting new ideas.
