A Dead Man in Istanbul (Seymour of Special Branch, #2)

When the second secretary of the embassy in Istanbul dies under suspicious circumstances, an officer of the Special Branch, known as Seymour, investigates the murder site at a passage between the European and Asian continents and discovers that the victim may have been involved in a politically charged operation. The Second secretary of the embassy in Istanbul has died in decidedly strange circumstances while attempting to swim the Dardanelles Straits, the passage between Europe and Asia, heavily used by warships, liner, tankers and cargo vessels of all kinds. A romantic attempt to repeat the legendary feat of Leander, as the embassy claims? Or an attempt to spy out a possible landing place for a British military expedition, as the Turks insist? Whichever, Cunningham has ended up with a bullet in his head
