“I can reconstruct those gyroscope plans!” cried the old man. “I remember most of them, though it will set me back very much to have them taken. Of course it’s a big loss, Tom. The whole chestful gone! How did it happen?” He was told, and then he confirmed Tom’s first idea that he had heard nothing during the night to indicate an attack on the shop. “I done t’ink I heard somethin’,” Eradicate said when they asked him about the matter. “It was a sort of hootin’, hollerin’ sound. But I figgered it was an owl bird, an’ I went to sleep again!” “That was probably Koku shouting at the robbers,” decided Tom. “He’s either still after them or they’ve done for him.” “Koku gone?” cried Rad, and when told him that the giant was missing the colored man forgot all his petty animosity against the big fellow and expressed only sympathy. “I’s gwine to find him!” declared Eradicate. “I go look for him!” Tom did not pay much attention to his colored helper, since there were other matters that needed his attention. The net result of the searching on the part of his men was nothing. There were no clews that could be followed. Reconstructing the crime, it was thought that the gang of men had gained entrance by means of a false key. Then, being unable to open the chest because of the special locks on it, they had carried it away. Surprised at this by Koku, they must have silenced the giant in some manner and have carried him off while he was unconscious. Doubtless an auto was used, though so many of these came and went at the Swift office that the tire marks of no special one could be picked out. “All that remains is for us to make a search,” suggested Tom. “And we have this much to go on—that I suspect my chest was stolen by the same men, or some representing them, whose offer I turned down when Mr. Damon made it on behalf of Mr. Blythe.” “Then why not have Mr. Damon over here,” suggested Mr. Swift. “He may be able to give us some clews as to these scoundrels.” “I’ll do it!” cried Tom, and he sent an airship for Wakefield Damon at once. “Bless my fire insurance policy, Tom Swift, but this is a terrible affair!” cried the odd man when he entered the office a little later. “I wouldn’t have had it happen for a million dollars! Bless my check book if I would! And it’s all my fault.” “How do you make that out?” asked Tom, with a smile. “I was foolish enough to bring you that offer from Mr. Blythe, though I took it in good faith, and never knew he was such a scoundrel! To think of his kidnapping Koku and taking your chest.”
