On 13 July 1910, Inspector Walter Dew of Scotland Yard called at 39 Hilldrop Crescent where, in the cellar, he found the remains of Cora Crippen. Married to Dr Hawley Harvey Crippen (pictured), a doctor of homeopathic medicines, Cora had been poisoned with hyoscine, the only time hyoscine has been used to commit murder.
The Crippen’s marriage had been stormy. A would be music hall singer, Cora had indulged in a number of affairs, while Dr Crippen had taken up with his secretary, Ethel Le Neve, a woman twenty-one years his junior. Inspector Dew suspected Dr Crippen of murder, but he couldn’t locate the doctor.
Meanwhile, on the SS Montrose, a steamship bound for Canada, the ship’s captain, Henry Kendall, became suspicious of two passengers, John Philo Robinson and his sixteen year old ‘son’; rightly so, because Crippen had shaved off his moustache while Ethel had cut her hair short and donned boy’s clothing.
Captain Kendall informed Scotland Yard. In haste, Inspector Dew boarded the SS Laurentic and moments before Dr Crippen and Ethel could disappear into the vast continent of North America, he arrested Crippen, the first man to be captured by wireless telegraphy.
