Nostalgic, witty and filled with characters and situations that people of all ages will recognise, Dear Lupin is the entire correspondence of a Father to his only son, spanning nearly 25 years. Roger Mortimer's sometimes hilarious, sometimes touching, always generous letters to his son are packed with anecdotes and sharp observations, with a unique analogy for each and every scrape Charlie Mortimer got himself into. The trials and tribulations of his youth and early adulthood are received by his father with humour, understanding and a touch of resignation, making them the perfect reminder of when letters were common, but always special. A racing journalist himself, Roger Mortimer wrote for a living, yet still wrote more than 150 letters to his son as he left school, and lived in places such as South America, Africa, Weston-super-Mare and eventually London. These letters form a memoir of their relationship, and an affectionate portrait of a time gone by.

Charlie Mortimer was born in 1952 and educated at Wellesley House, Broadstairs and (reluctantly) Eton. He has been, among other things, an officer in the Coldstream Guards, a vintage car restorer, an estate agent, a roughneck on an oil rig, a pop group manager, a mechanic in Africa, a manufacturer of boxer shorts and an antiques dealer. He currently describes himself as a 'middle aged, middle class spiv (mostly retired)'
