Sianโs mission to get to the truth behind Helen Duncanโs apparently supernatural abilities draws to a close โ but a secret package sent from Helenโs granddaughter in America leaves Sian with what appears to be the smoking gun she has been waiting for. The package contains what seems to be unexplainable proof that a 'spirit' revealed the sinking of a second warship during one of Helenโs sรฉances. But this time, the sรฉance happened before even the government was aware. Sian tussles with the few explanations still on the table โ was this information received from beyond the grave? Or could Helen Duncan have been a spy and in league with the enemy? Wherever the truth lies, Sian feels increasingly sure there was more to Helenโs Old Bailey trial and conviction than a case of fraud.
