Winner of the 2014 Finlandia Prize A FAMILY UNDER THREAT. A FATHER'S WORST NIGHTMARE... On the surface, Joe Chayefski has it all. A great job, a beautiful wife and two perfect daughters. But when the lab he works in as a neuroscientist is attacked, Joe is forced to face the past and reconnect with the son he abandoned twenty years earlier. As Joe struggles to deal with the sudden collision of his two lives, he soon finds he needs to take drastic action to save the people he loves. Gripping and suspenseful, They Know Not What They Do skilfully weaves together the big issues of the day- the relationship between science and ethics, and people's increasing inability to communicate - into an ambitious page-turner of a novel.
