The Mummy and Miss Nitocris by George Griffith

In all London, or, indeed, in any capital of Europe, there were no more angrily puzzled men than Nicol Hendry and his colleague and subordinates. He was perfectly certain now that Phadrig Amena held the key to the conspiracy which had resulted in the disappearance of Prince Zastrow. Oscarovitch had vanished. He had been traced to Copenhagen, and then absolutely lost sight of. Three agents, all picked experts, had been put on to watch Phadrig and the Pentanas, as they were known to him, and within a fortnight they had all died. One had fallen down crossing the north side of Trafalgar Square: the verdict had been heart failure. Another threw himself into the river from the Tower Bridge; and the third, a woman who was one of the most skilful spies in the service of the International, had made his acquaintance and had dinner with him at the "Monico," and was found dead the next morning with an empty morphia syringe in her hand and a swollen puncture in her left arm.

Thus four more or less valuable lives had been lost, and not a shred of tangible evidence obtained against the Egyptian. Convinced as he was that this man was as responsible for their deaths as he had been for that of Josephus, neither he nor his colleagues could find the slightest grounds for applying for a warrant for his arrest, and meanwhile things were going from bad to worse in Russia. The Romanoff dynasty was tottering to its fall. The responsible leaders of the Revolution, angry and bewildered by the loss of the man whom they had practically chosen to rule over them, were distributing thousands of copies of an unsigned manifesto which could not have come from any one but "the new Skobeleff. " What was left of the army and the navy was rallying to the nameless standard of the still unknown saviour of Russia. Von Kessner and Captain Vollmar had apparently ceased to exist, and the Princess Hermia was living with her lady-in-waiting in the strictest retirement in Dresden.
