Howard Jacobson is a writer of consummate skill and his most recent novel with its shortest of all possible title J [London: Jonathan Cape, 2014] was shortlisted for the Man Booker Prize. He won that prize in 2010 with the extremely witty and wonderfully funny The Finkler Question. Jacobson is very much a Jewish writer with Jewish characters, often it seems doppelgänger for the author, and Jewish themes and problems as the main strands of their narratives. However, he writes from a cultural rather than a religious perspective. So; what to make of J which one could say conforms to this pattern? That is a harder than usual question.
