Famous Trials: Unwanted Spouses

Thomas Cream, erstwhile Sunday school teacher and serial poisoner, has an unsettling air and wonky eye. He also happens to be a doctor, which provides him with ample means and an ideal cover for his murderous activities. His victims are vulnerable young women, whose trust he gains with drinks and trips to the music hall, before offering them pills or swigs from a medicine bottle. A few hours later, they are dying in agony.

The Honourable Thomas Ley, meanwhile, has an even better disguise: he's the former Justice Minister for New South Wales and a successful businessman, albeit with a shady past. Rumours abound when a political opponent disappears without trace and a business partner winds up at the bottom of a cliff.

Neither killer can help themselves - and this, in the end, leads to their downfall - and both defy our comprehension. Brilliantly reconstructed here, their trials, in 1892 and 1947, reveal a deeply sinister conundrum: by the time you've discovered the secrets in their heart, it's inevitably much too late.
