There were a thousand questions he wished to ask, and only the last could Jim answer. He took his friend to the copper gauze stretching across the window, which was otherwise devoid of covering, for no glass was employed, and again with the help of the lamp showed him a neat little round hole punched through the gauze. "He stood outside there and stared in at us," he said, putting the events as he guessed them. "He cocked his pistol, and we heard the noise. Then he fired as we got to the door. Queer, isn't it, Mr. Phineas?" "Queer! It's downright, cold-blooded attempt at murder!" shouted Phineas. "Call those boys." But there was no need to summon them. Tom and Sam were already at the door, while Ching was in the passage, a swaying lantern in his hand. "What dat?" asked Tom, his eyes beginning to bulge. "Someone fire a shot. Tom not like dat at all; he tink someone try to kill him." "Boys," said Phineas, keeping perfectly cool, "some scoundrel came to the window of the parlour and fired at Jim here. He missed him by an inch. We must follow and take the fellow, whoever he may be; it may be the work of a lunatic. Bring along that lamp, Ching." "One moment!" cried Jim. "Best leave someone here in case the fellow returns. Tom, you look after the house. I can trust you to frighten anyone away. Sam and Ching will come with us. Sam, we want you to open those eyes of yours extra wide: that fellow must be followed. Now, are we ready? But first, has anyone seen a stranger about here to-day?" "Seed a nasty-lookin' Spaniard, I did," admitted Sam, his eyes shining bright and eager in the lamplight. "Him one of de crowd working on de canal I tink; but me recognize him. Same man aboard de steamer, sah; yo knock him down when he come for yo wid a knife. Yo go bang, squelch! Him flop over on to him back, den creep away growling out, and sayin' tings beneath him breath. Him nasty fellow altogether." "Then there is the motive for the crime," declared Phineas at once. "There is never any telling what some of these Southerners will do. No doubt, in the course of the fight aboard the ship, you knocked him down, though from the look of your face you evidently don't remember the matter. See here, Jim; let Tom go with you. I forgot that I have a broken arm, and am more likely to delay you; but I'll telephone down to the police headquarters in Colon, and put them on the watch. I suppose you'll follow?" Jim nodded promptly. "At once," he said with decision. "If I passed the matter now, he would make a second attempt, and I don't much fancy that. Sam's a splendid tracker, and if there's a mark he will be able to find it. Then come along, boys. Ching, bring the lamp; perhaps there's another we can have?" It took but a few minutes to discover another lamp, then the party set out. Meanwhile the diminutive Sam, his eyes sparkling with enthusiasm, had been moving swiftly about the house outside.
