Ripper Street
Ernest Manby, a 60-year-old toy maker, is beaten to death for a mysterious brass box and the coins in his pocket.
The Whitechapel Vigilance Committee presents a culprit in the form of 14-year-old Thomas Gower, who refuses to deny the charge. Reid – his conscience challenged by a radical lawyer called Eagles and orphanage Governess Deborah Goren – tests the security of the case.
Meanwhile, Jackson’s drinking and gambling have led to the loss of the pendant that ties him to his American past – a past that he and Long Susan fear will now be exposed. Reid and Drake find themselves besieged at Miss Goren’s orphanage by the rest of Gower’s vicious child gang and their brutal master, Carmichael.
