The Case of the Displaced Detective: The Arrival is a science fiction mystery in which the brilliant hyperspatial physicist, Dr. Skye Chadwick, discovers that there are alternate realities, and said alternates are often populated by those we consider only literary characters. Her pet research, Project: Tesseract, hidden deep under Schriever AFB, is her means of looking in on these continua. In one particular reality, continuum 114, a certain Victorian detective (who, in fact, exists in several continua) was to have died along with his arch-nemesis at the Reichenbach Falls. Knee-jerking, Skye intervenes, rescuing her hero, who inadvertently flies through the tesseract wormhole connecting his universe with ours, while his enemy plunges to his death. Unable to send Holmes back without causing devastating continuum collapse due to non-uniqueness, he must stay in our world and learn to adapt to the 21st century.

Meanwhile, the Schriever AFB Dept of Security discovers a spy ring working to dig out the details of – and possibly sabotage – Project: Tesseract.

Can Chadwick help Holmes come up to speed in modern investigative techniques in time to stop the spies? Will Holmes be able to thrive in our modern world? Is Chadwick now Holmes' new "Watson" – or more?

And what happens next?
