Lincoln, 1380. A raven-haired widow is newly arrived in John of Gaunt’s city with her two unnaturally beautiful children in tow.

The widow Catlin seems kind, helping wool merchant, Robert of Bassingham, care for his sick wife. Surely it makes it makes sense for Catlin and her family to move into Robert’s home?

But when first Robert’s wife – and then others – start dying unnatural deaths, the whisper turns to witchcraft.

The reign of Richard II brings bloody revolution, but does it also give shelter to the black arts? And which will prove more deadly for the innocents of Lincoln?
