Most maths books are deadly serious.
They are also deadly boring - full of algebra, equations and absolutely no jokes. But the Murderous Maths books are different. They have the power to make you laugh. Kjartan Poskitt has a name that s hard to spell, a sense of humour totally in tune with his readers and a wonderful array of off-beat characters who populate a world where maths is always popping up. My personal favourite is Pongo MacWhiffy but the delightful band of inept gangsters come a close second and Professor Fiendish is hard to forget.
