"A quarter-past nine," he replied. "You turn in, Chalmers. I'll take first trick."

The petty officer, having eaten his share of the scanty repast, was soon sound asleep. Fordyce, having made up the fire, prepared to keep watch, not knowing what move his captor might make.

It was close on midnight when he heard his name called. Hardly able to credit his senses, the Sub started to his feet. The voice seemed familiar, yet he could not fix the speaker's identity.

Relighting the lamp, and without disturbing his sleeping companion, the Sub hastened along the passage. Suddenly he halted. The trap-door above his head was opened, and through the aperture could be seen the head and shoulders of a man. His features were muffled in a turned-up fur collar, while an astrakhan cap was drawn well down over his forehead; but, in spite of this, Fordyce was now able to recognize the man.

It was Mindiggle.

CHAPTER XXIV

Fordyce's Two Visitors

A seemingly very slight incident will freqently alter the course of a man's career, and throw his time-table completely out of gear.

It was thus in the case of Ernz von Verbrennungsraum, otherwise the trusted and respected Town Councillor Mindiggle of Otherport.

When he vainly attempted to trade upon Noel Fordyce's affection for his dog, Mindiggle had no intention of proceeding to Russia. It was only after his conversation with his fellow-conspirator, Boris Platoff, that he decided to go to Petrograd and hand over in person a small but immensely-powerful stock of nitro-talcite to the Extremist leader, Vladimir Klostivitch.
