Lestrade and the Ripper

Book three in the Inspector Lestrade series. In the year 1888, London was horrified by a series of brutal killings. All the victims were discovered in the same district, Whitechapel, and they were all prostitutes. But they weren't the only murders to perplex the brains of Scotland Yard. In Brighton, the body of one Edmund Gurney was also found. Foremost among the Yard's top men was the young Inspector Sholto Lestrade and it was to his lot that the un-solved cases of a deceased colleague fell.
Cases that included the murder of Martha Tabram, formerly a prostitute from Whitechapel, and that of the aforementioned Gurney. Leaving no stone unturned, Lestrade investigates with his customary expertise and follows the trail to Nottingham-shire, to a minor public school, Rhadegund Hall. It is his intention to question the Reverend Algernon Spooner. What he finds is murder. As the Whitechapel murders increase in number, so do those at Rhadegund Hall and so do the clues.
What is the connection between them all? As if it weren't confusing enough, Lestrade is hampered by the parallel investigations of that great detective, Sherlock Holmes, aided by Dr Watson. Who is the murderer of Rhadegund Hall and are he and the man they call 'Jack the Ripper' one and the same?
