At last the words came, and Maxime’s face flushed with triumph as he heard them. “What does the Brotherhood require?” the Professor asked hollowly. The younger man stretched out his hand to the great globe that stood beside him and twirled it on its axis. “In March, just two years ago,” he began, “the ship _Orkney_ sailed from London for St. Petersburg with five millions in gold on board, consigned to the Russian government. It was the people’s gold, borrowed on the people’s credit, to aid in enslaving the people. We swore it should never reach St. Petersburg. We kept our word. The _Orkney_ was wrecked in the night in the Gulf of Bothnia--no one survived to tell where. Russia long sought for it in vain. We ourselves sought for it in vain. But now, at last, a clue has reached our hands.” “Well?” “It is not perfect yet, but it will be. Marie Fitzhugh, our agent, will be here in a few hours, and will forge the last links. Her task is difficult, but she will succeed. By one means or another, she will succeed. I would have waited till she had finished her part before seeing you, but I have been ordered to another duty and must leave to-night. So she herself will send you word--perhaps to-morrow. If not to-morrow, soon after.” “Well?” “If she succeeds, we shall be able to go to the spot and get the gold. If she fails, we nevertheless shall know approximately where to look for it. But, as you are aware, no vessel can dredge in the Baltic without being watched. We do not want to find the gold for Russia to seize. So we come to you for help.” “What?” Amazement showed in Professor Shishkin’s face and voice. “Are you serious?” he demanded. “Why not? You have spent a lifetime studying the sea. You have made a specialty of the Baltic. You have won a great name by your work there. What more natural then than that you should revisit your chosen field? What more natural than that you should take divers with you to explore the sea-bottom? You, and you alone, of all the Brotherhood, can do this without suspicion. You, and you alone, can get the gold safely on board after it is found.” “But----” “There are no buts when the Brotherhood speaks, and it has spoken. If the task be difficult, the more honor in accomplishing it. A ship will be provided, manned, and equipped. Your sole duty is to prepare such apparatus as you may need for your scientific work, and to spread abroad the alleged object of your trip. Probably you had better send an announcement of it to the newspapers. Of course you will not do this until Marie notifies you.” “Very well.” “One thing more,” went on the messenger, gravely. “I am instructed to command you to take your daughter with you. Her presence will add force to your declaration that the trip is purely scientific.” The Professor shook his head. “I cannot do it,” he declared. “I cannot and will not take Olga to Russia, under any circumstances. You know why.” “The Brotherhood commands it.” “I will appeal.”
