The history of crime detection has produced no more famous name than that of Sexton Blake

William Franklyn stars as paperback hero Sexton Blake, with David Gregory as his assistant Tinker, in four original BBC Radio dramatisations from 1967. Lost from the BBC archives for over 40 years, these rediscovered episodes are presented for the very first time.

The Vampire Moon: Sexton Blake and Paula Dane are out at a London restaurant, when one of their fellow diners suddenly collapses. His dying words warn of the danger of the Vampire Moon. Featuring Marjorie Westbury (Paul Temple).

The Fifth Dimension: Harry Monkton wins 84,000 on the Pools. Then, one day, the phone rings and he disappears

First Class Ticket to Nowhere: Lost in the fog, Sexton Blake and his friends stumble across a deserted railway station. Then theres a gunshot

Plus a special bonus episode – Murder on the Portsmouth Road. In one of Britains earliest surviving drama recordings (from 1930), Arthur Wontner stars as Sexton Blake, tracking down a killer on a stormy night.
