When Eve Carpenter lands with a splash in the Thames, it’s not the London or England she’s used to. No one has a telephone or knows what a computer is. But worst of all, everyone thinks Eve’s a spy. Including Major Harker, who has his own problems. The general wants him to undertake some ridiculous mission to capture a computer, which Harker vaguely envisions running wild somewhere in Yorkshire. Turns out the best person to help him is Eve. Eve knows all about computers, and electricity. There’s every possibility she’s mad… And Harker is falling in love with her.
