'The Finkler Question' is a story of friendship and loss, exclusion and belonging, and of the wisdom and humanity of maturity. The book presents Julian Treslove, a professionally unspectacular former BBC radio producer, and Sam Finkler, a popular Jewish philosopher, writer and television personality, what are old school friends. Despite a prickly relationship and very different lives, they've never quite lost touch with each other - or with their former teacher, Libor Sevcik, a Czech always more concerned with the wider world than with exam results.
