A Dead Man in Athens

Athens, 1913, the capital of a country on the brink of war. The new Greek prime minister, Venizelos, tired of the Ottoman overlords, has what he calls the Great Idea - a vision of a new Greece that unites all the Greek people scattered around the Mediterranean. Not such a great idea, in the view of other countries, among them Britain, which believes in letting sleeping dogs lie. And cats. Including the one recently poisoned in Athens and which belonged to the exiled former Sultan.
Unfortunately, as is the way with the Balkans, rumours start flying around; one being that this was a sighting shot for the ex-Sultan himself. This, in the Balkans, could start a war and so Britain has to sit up and take notice. Something has to be done. Fast. And - please, urge the diplomats - low-key. The lowest key of all is to send out a police officer from Scotland Yard to investigate, and, as it happens, the Foreign Office has a person in mind: Seymour, of the CID, who has had some experience of this sort of thing before .
