So I recounted, as briefly as I could, the events of the past two days, and the happy accident which had given me the address I sought. Mr. Royce's face was beaming when I ended. "And you start for France to-morrow?" he asked. "To-morrow morning--the boat sails at ten o'clock." "Well, I'm going with you!" he cried. "Why," I stammered, startled by his vehemence, "are you strong enough? I'd be mighty glad to have you, but do you think you ought? How about it, doctor?" Jenkinson was smiling with half-shut eyes. "It's not a bad idea," he said. "He needs rest and quiet more than anything else, and he's bound to get a week of that on the water, which is more than he'll do here. I can't keep that brain of his still, wherever he is. He'd worry here, and with you he'll be contented. Besides," he added, "he ought to be along: for I believe the expedition is going to be successful!" I believed so, too; but I recognized in Jenkinson's words that fine optimism which had done so much to make him the great doctor he was. I shook our junior's hand again in the joy of having him with me. As for him, he seemed quite transformed, and Jenkinson gazed at him with a look of quiet pleasure. "You'll have to pack," I said. "Will you need my help?" "No; nurse can do it, with the doctor here to help us out," he laughed. "You've your own packing to do, and odds and ends to look after. Besides, neither of us will need much luggage. Don't forget to reserve the other berth in that stateroom for me." "No," I said, and rose. "I'll come for you in the morning." "All right; I'll be ready." The doctor followed me out to give me a word of caution. Mr. Royce was still far from well; he must not over-exert himself; he must be kept cheerful and hopeful, if possible; above all, he was not to worry; quiet and sea air would do the rest. I hurried back to the office to make my final report to Mr. Graham, and to get the abstract which Rogers had promised to have ready, and which was awaiting me on my desk. Our worthy senior was genuinely pleased when he learned that his junior was going with me, though our absence would mean a vast deal of extra work for himself. The canvass of the city stables had been completed without result, but I suspected now that Martigny himself had hired the carriage, and had, perhaps, even acted as driver--such an easy and obvious way to baffle our pursuit would hardly have escaped him. I finished up some odds and ends of work which I had left undone, and finally bade Mr. Graham good-by, and started for my rooms. My packing was soon finished, and I sat down for a final smoke and review of the situation.
