"I hope, with all my heart, it may not be," he replied, and then the cab they had engaged rattled away over the stones and was soon lost to view. The Countess's stay in Naples was a short one, for next morning she left by an early train for Rome. According to the plan he had prepared, His Grace of Rotherhithe, having made enquiries as to the trains leaving Naples for the capital, was present on the platform when the first took its departure. With an eagerness that could only be accounted for by his infatuation, he scanned the faces of the passengers, but the lady for whom he had been so anxiously waiting was not among them. Greatly disappointed by his discovery, he went off in search of breakfast, only to return a quarter of an hour before the next train was due to leave. Unfortunately, on this occasion, he was no more successful than before. The train was well filled, but among the passengers there was not one who bore any sort of resemblance to the lady he was hoping to see. So anxious was he to make sure that he did not miss her, that, just before the train started, he came within an ace of being run into by an invalid chair, in which was seated a man closely muffled up with shawls. By the side of the chair walked a nurse in English hospital uniform, who wore large blue glasses, and carried more wraps and a couple of cushions upon her arm. Even had he been aware of their identity, the Duke would have found it difficult to recognise in the pair his guests of the previous day. It was not the first time in their careers that they had been compelled to adopt such disguises, and only that morning news had reached them to the effect that, if they desired to get safely out of Naples, disguises such as they had assumed would be imperative necessities. A carriage, it appeared, had been reserved for the invalid Englishman, and towards it they made their way. Having seated the old gentleman in one corner, the nurse took her seat opposite him, and busied herself preparing for the journey. It was not until Naples was far behind, however, that she removed her spectacles and the invalid discarded his wraps. "That was as narrow an escape as we have ever had," said the former. "The Head of the Police was upon the platform, and I recognised two detectives in the crowd. However, all is well that ends well, and if Luigi's arrangements have been properly made, we should be in Paris before they know we have left Naples, and in London forty-eight hours afterwards." "Then you still feel certain that they were aware of our presence in Naples?" "Luigi's message said there was no doubt about it. Though he did not know it, they must have been watching him, and have followed him to the yacht. It was foolish of him to run such a risk. Let us hope, however, he will be able to get out of Naples without their laying hands upon him."
