June 1939. England is partying like there is no tomorrow, gas masks at the ready ... but the good times won’t last. In Europe, the Nazis have invaded Czechoslovakia, and in Germany Jewish persecution is rife. Closer to home, the IRA has embarked on a bombing campaign throughout Britain.
But the most far-reaching event of all goes largely unreported: in Germany, Otto Hahn has made the atomic bomb possible. German High Command fears that Cambridge’s Cavendish Laboratory could be close behind; they must discover its secrets before it is safe to wage war.
When one of the Cavendish’s finest brains is murdered, Professor Tom Wilde is drawn into the investigation. He unveils a conspiracy in which the fate of the world rests on the discovery of a kidnapped child. Can Tom Wilde discover the truth before it is too late?
