A book about a Quaker who poisoned his mistress to cover up their affair will be published next month.
John Tawell lived in Berkhamsted after spending 15 years exiled in Australia for forgery. He had two children with mistress Sarah Hart, but killed her when supporting them became a financial struggle.
He was the first person arrested after a telegraph alert, after police alerted railway colleagues that he was travelling to London by train. He was hanged in 1845. The book –The Peculiar Case of the Electric Constable by Carol Baxter – is due out on September 5.
