Howard Jacobson the eldest son of MAX JACOBSON the Manchester conjuror, made a late but successful start in the world of fiction. At the age of 41 he published Coming from Behind a scabrous satire of polytechnic life; and now, with his sexual comedy Peeping Tom he has established himself as an important new voice in English fiction. Tonight Arena looks at this Leavisite polytechnic lecturer, shopkeeper and original Jewish humorist on the move from Manchester, Wolverhampton, Cornwall and Australia.
