Has the faintest whiff of W.G. Sebald; haunted characters determined to pull others down into turbid, oppressive currents of memory and ideas. You are willingly drawn down with them
Lagercrantz neatly intertwines the facts of Turing's life with the fiction of Corell's quest for knowledge to create an unsettling story of state secrets and sexual hypocrisy
Absorbing . . . Gets the synapses sparking . . . Lagercrantz is at home with a damaged hero who has more of an affinity with computers than humans
A persuasive evocation of Turing's genius and of a Britain still suffering under rationing and repression
Perhaps the most signal achievement here is the clever melding of two narrative forms: a sympathetic biography of a real historical figure treated appallingly by the establishment, and a police procedural in which a dogged copper tries to crack a mystery in the teeth of bloody-minded intransigence
Swedish crime fiction moves into Britain's heartland in this superbly written espionage and murder novel . . . Lagercrantz has the lingo, the mood and the place down pat.
