Thomas needs to speak to his mother before she dies. But he's set to give a talk to a conference of physiotherapists in the Netherlands; if he leaves now will he get to her deathbed in time? Will he be able to say what he couldn't say before? He can't concentrate on what is happening now: his mind won't sit still. Should he try to solve his friend's marital crisis? Should he reconsider his separation from his own wife? And why does he need to pee again? In Extremis is Tim Parks's masterwork: a darkly hilarious and deadly serious novel about infidelity, mortality and the frailties of the human body.
