Gwen, girl-like, was all excitement at the prospect of this flying journey to the south. At one moment she endeavoured to reassure me that nothing was wrong, while at the next she expressed wonder at the motive of the mysterious message. At last, however, we found ourselves seated in the corners of a first-class carriage, slowly crossing the Thames on the first stage of our dash to Italy. The outlook was grey and cheerless, precursory, indeed, of a dismal conclusion to our journey to the far-off land of sunshine. We got out at Folkestone Harbour, however, well to time, and that evening were fortunately only seven minutes late in arriving at the Gare du Nord. We had dined in the train, so, therefore, entering a taxi-cab, we were soon whirled across Paris to the Gare de Lyon, where we had only eight minutes to spare before the departure of the _rapide_ for Rome. All that night, as I lay alone in my sleeping-berth while the great express rocked and rolled on its way to the Alpine frontier, my mind was full of gravest apprehensions. Gwen had been given a berth with another lady at the further end of the car, and I had already seen that she was comfortable for the night. Then I had turned in to spend those long dreary hours in wakeful fear. I could discern no motive for inveigling my wife--with whom Kirk had never spoken--to a destination abroad. Yet one curious point was quite plain. That mysterious dweller in Bath Road--the man with the pet parrot--was well aware of my absence in the north. Otherwise he would not have forged my name to a message sent from Turin. For what reason could he desire Mabel's presence in Florence? He must have some object in her absence. Perhaps he foresaw that her absence meant also my absence--and that my enforced journey meant a relaxation of the vigil I had established upon the man who had gone north on the night of the Professor's assassination. That was the only feasible theory I could form, and I accepted it for want of any better. But in what a whirlwind of doubt and fear, of dark apprehensions and breathless anxiety I now existed you may well imagine. Gwen, looking fresh and bright and smart in her blue serge gown, came to me next morning, and we had our coffee together at a wayside station. Though we sat together through the morning hours until we stopped at the frontier at Modane, she refrained from referring to the reason of Mabel's call abroad. The young girl was devoted to her sister, yet she did not wish to pain or cause me any more anxiety than was necessary. After passing through the great tunnel, emerging on the Italian side and coming to Turin, where we waited an hour, the journey became uneventful through the afternoon and evening until the great bare station of Pisa was reached, shortly before midnight.
