​B. Traven's​ novels and stories​ have sold m​ore than ​3​0 million copies​ over the past century in more than 30 languages​ worldwide. He was Einstein's favourite novelist. Der Spiegel ranks his The Death Ship as the third greatest German novel ever written (okay in the past 100 years), after Thomas Mann's The Magic Mountain, and Kafka's The Castle; and yet, despite this, few today, in the English speaking world at least, have heard of him. It's only thanks to the movie, The Treasure of Sierra Madre, based on one of his stories, that he's known here at all. Why is this? Perhaps because no-one knows with absolute certainty who Traven was. No-one is 100% sure of his true identity. Timothy Heyman ​(CBE​) is 99% sure. We talk here about his hypothesis, plus the tasks he's set himself to re-establish Traven's reputation and re-gain an audience for his works. Heyman, a considerable person in his own right, is co-manager (recently promoted to managing director) of the B. Traven Estate along with his wife (who is proprietor), Malú Montes de Oca de Heyman​, Traven's stepdaughter. I met Tim up in the couple's beautiful apartment overlooking Mexico City to talk about what he's achieved to date with Traven's literary archive, and, again, who he thinks Traven really was. We were surrounded by a library of books written by the mystery man, accompanied by a glorious panoramic view of the city. After our conversation we went upstairs to a special room which holds the archive - the place where Tim occupies himself with the business of legacy building.
