      Finger Prints was published. In it, he demonstrated that the chance of two sets of prints being identical (a ‘false positive’) was about 1 in 64 billion. In consequence, it was Galton who was given the credit for establishing fingerprinting as a ‘major system of identification in forensic terms’ (Nigel McCrery, 2013).

      The first use of fingerprints to solve a murder in Britain took place in March 1905 in Deptford, London. Mr Farrow and his wife had been attacked and left for dead and the weekly takings had been stolen. Chief Investigator Melville Macnaghten (1853–1921) found a fingerprint on an inside tray of the cash box. Detective Inspector Charles Stockley Collins (dates unknown) examined the print, and established that it did not match the Farrows’ prints, nor any of

      those on file (c. 80,000–90,000 at the time). Eventually, a vagabond named Alfred Stratton (1882–1905) was identified as a likely suspect along with his brother Albert (1884–1905). The print matched Alfred’s right thumb and he was charged with murder. They were convicted of murder at the Old Bailey and hanged on 23 May 1905.

      In the 1800s, it was not scientifically possible to distinguish different blood types, or even whether blood was human or animal.

      In London in 1888, throughout the Jack the Ripper murders, the killer could have walked around Whitechapel covered in the blood of his victims, safe in the knowledge that it could not be used to convict him. It was not until 1901 that a German scientist named Paul Theodore Uhlenhuth (1870–1957) developed an efficient test to identify human blood, the basis of which is still in use by police today.

      This book begins with one of the most celebrated murders of the pre-Victorian age, the Ratcliffe Highway murders of 1811. The slaughter of two families within a week of each other within a small area outraged Londoners and led to early calls for police reform. The period covered by this volume ends in 1910 with the arrest of Hawley Harvey Crippen (1862–1910) for the murder of his wife, Cora – the first arrest to be made through the use of the wireless telegraph. •
