About this audiobook
A voice speaks from a locked and empty room. Its owner is miles away, and the warning is unmistakable.
In the winter of 1894, governess Eleanor Whitmore comes to 221B Baker Street with coded letters and an impossible story. She heard Sir Victor Blackwood threaten someone from behind a locked drawing-room door, even though he was speaking before Parliament at that exact hour.
Sherlock Holmes proves the voice was no ghost. It was part of an ingenious scheme involving a concealed phonograph, Parliamentary secrets, coded correspondence, and a financial conspiracy four years in the making.
But Sir Victor may not be the true mastermind. Someone else is watching the household, manipulating the evidence, and turning a respected politician into the instrument of a more dangerous design.
The Blackwood Cipher is Book One of The Sherlock Holmes Untold Case Files, featuring Sherlock Holmes and Dr. John H. Watson.
