A senior officer is assigned to the case after Erast Fandorin is attacked in the street.
Fandorin goes undercover to visit a notorious gambling den.
Fandorin has travelled from Moscow to The Winter Queen Hotel in London on the trail of the elusive Cleopatra.
Betrayed by a traitor in the Russian Embassy, Fandorin is bound, gagged and on the way to a watery grave in the Thames.
The trail has led Fandorin back to St Petersburg, where he is delighted to meet up with his Chief, Ivan Brilling.

In the concluding episode of Boris Akunin's best-seller, Fandorin has tracked down the leader of the organisation Azazel, but his life remains in peril.
