The explanation of what had been a most unpleasant mystery was so very simple and natural, that the past fright and apprehension seemed almost like a take-in. It shall be given at once; though the reader will readily understand that at present Hamish knew nothing of the details, only the bare fact that Arthur was alive and well. He would have to wait for them until Arthur's return. Amidst the letters handed to Arthur Channing by the waiter of the hotel that night in Norfolk Street, was one from Marseilles, stating that Charles, just before landing, had had a relapse, and was lying at Marseilles dangerously ill--his life despaired of. Perhaps in the flurry of the moment, Arthur did not and could not act so reasonably as he might have done. All his thoughts ran on the question--How could he in the shortest space of time get to Marseilles? By dint of starting on the instant--on the instant, mind--and taking a fleet cab, he might get to London Bridge in time to catch the Dover mail-train. Taking up his hat and letters, he ran out of the coffee-room calling aloud for the waiter. Nobody responded: nobody, as it would appear, was at that moment in the way to hear him. Afraid of even an instant's detention, he did not wait, but ran out of the hotel, up Norfolk Street, hailed a passing hansom, and reached London Bridge Station before the train started. From Dover to Calais the boat had an exceedingly calm passage, and Arthur was enabled to write some short notes in the cabin, getting ink and paper from the steward: one to the hotel that he had, as may be said, surreptitiously quitted, one to Hamish, one to Roland, one to Mr. Galloway, one to Mr. Galloway's London agents. Arthur, always considerate, ever willing to spare others anxiety and pain, did not say _why_ he was hastening to Marseilles, but merely stated that he had determined on proceeding thither, instead of awaiting Charles in London. These letters he gave to a French commissionaire on landing in Calais, with money to buy the necessary stamps, and a gratuity to himself; ordering him to post them as soon as might be. Whether the man quietly pocketed the money and suppressed the letters, or whether he had in his turn entrusted them to someone else to post, who lost, or forgot them, would never be ascertained. Arthur, all unconscious of the commotion he was causing at home, arrived quietly at Marseilles, and there found Charles very ill, not quite out of danger For some days he was wholly occupied with him, and did not write at all: as he had said nothing about the illness, he knew there could be no anxiety. Now that he did write, Charles was getting better rapidly. It may just be observed, that the letter left in the rack of the hotel (that came on with the rest of the steamer's letters from Marseilles) had served to complicate matters; but for that letter it would have been surmised that Arthur had received unfavourable news of Charles, and had gone on to him.
