It must have been one of the last cartoons he drew before he was murdered. The editor of Charlie Hebdo – Stephane Charbonnier who signed his work Charb – sent it to me as a sort of personal message welcoming me as a new subscriber to his magazine. The subscription was, as it happened, a Christmas present from my granddaughter Maisie Dubosarsky who lives and works in Paris but was home for Christmas, and from her boy friend Simon Fieschi, the web-master of Charlie Hebdo.
