In half an hour Serge came back to finish the reading of the will with her. The little slip of paper had been removed so skilfully that it would have been impossible for him to have even guessed that it had ever been attached to the parchment, or that it was now lying hidden in the bosom of the girl who would have killed him without the slightest scruple to gain the unsuspected possession of it. CHAPTER IV. A SON OF THE GODS. ON the day but one following the reading of Paul Romanoff’s secret will, Olga and Serge set out for St. Petersburg, to convey his ashes to their last resting-place in the Cathedral of SS. Peter and Paul in the Fortress of Petropaulovski, where reposed the dust of the Tyrants of Russia, from Peter the Great to Alexander II. of Russia, now only remembered as the chief characters in the dark tragedy of the days before the Revolution. The intense love of the Russians for their country had survived the tremendous change that had passed over the face of society, and it was still the custom to bring the ashes of those who claimed noble descent and deposit them in one of their national churches, even when they had died in distant countries. The station from which they started was a splendid structure of marble, glass, and aluminium steel, standing in the midst of a vast, abundantly-wooded garden, which occupied the region that had once been made hideous by the slums and sweating-dens of Southwark. The ground floor was occupied by waiting-rooms, dining-saloons, conservatories, and winter-gardens, for the convenience and enjoyment of travellers; and from these lifts rose to the upper storey, where the platforms and lines lay under an immense crystal arch. Twelve lines ran out of the station, divided into three sets of four each. Of these, the centre set was entirely devoted to continental traffic, and the lines of this system stretched without a break from London to Pekin. The cars ran suspended on a single rail upheld by light, graceful arches of a practically unbreakable alloy of aluminium, steel, and zinc, while about a fifth of their weight was borne by another single insulating rail of forged glass,--the rediscovery of the lost art of making which had opened up immense possibilities to the engineers of the twenty-first century. Along this lower line the train ran, not on wheels, but on lubricated bearings, which glided over it with no more friction than that of a steel skate on ice. On the upper rail ran double-flanged wheels with ball-bearings, and this line also conducted the electric current from which the motive-power was derived.
