In a new tale by Jonathan Barnes, Nicholas Briggs stars as the great detective with Richard Earl as Dr John Watson, in Sherlock Holmes – The Master of Blackstone Grange, coming out later this month.

The arrival at Baker Street of a client who, unusually, seeks advice from both men brings to their attention the existence of an isolated manor house in the east of England known as Blackstone Grange. The place, for so long the locus of wild rumours of witchcraft and sorcery, has acquired a very modern new master – a charismatic socialite named ‘Honest’ Jim Sheedy, a man of boundless ambition whose influence over British society appears, inexplicably, to be growing.

The detective learns that Colonel Sebastian Moran, released early from prison, travels to meet with Sheedy on the very day of his freedom. But curiosity curdles into obsession when Mycroft warns his brother, in the strictest possible terms, against investigating any further.

There’s a special treat for Sherlock Holmes listeners with this release. All pre-orders of Sherlock Holmes: The Master of Blackstone Grange will unlock a download exclusive of a festive tale – Sherlock Holmes: The Adventure of the Fleet Street Transparency – available now.

London at night.

Westminster, at the end of the age of empire. And here, two days before Christmas… an extraordinary mystery is about to unfold…

Footprints in the snow, an unfathomable assault in a Turkish bath… Watson is baffled, but Holmes has a growing suspicion that a seemingly fantastical encounter will become a reality.
