“The cave man method is fairly beastly, even when the cave man does his own kidnapping. When he sends an anthropoid ape to do his dirty work, it passes into another category.” The man’s eyes were invisible now; his face had grown a deeper hue. “So that’s your line, is it?” he said. “I thought you were a pal.” “I’m not responsible for your illusions,” said Michael. “Only I tell you this”—he tapped the man’s chest with his finger—“if any harm comes to Adele Leamington that is traceable to you or your infernal agent, I shan’t be contented with shooting Mr. Bhag; I will come here and shoot you! Do you understand? And now you can tell me, what is the meaning of that scream I heard from your tower?” “Who the hell do you imagine you’re cross-questioning?” spluttered Penne, livid with fury. “You dirty, miserable little actor!” Michael slipped a card from his pocket and put it in the man’s hand. “You’ll find my title to question you legibly inscribed,” he said. The man brought the card to the table-lamp and read it. The effect was electrical. His big jaw dropped, and the hand that held the card trembled so violently that it dropped to the floor. “A detective?” he croaked. “A—a detective! What do you want here?” “I heard somebody scream,” said Michael. “One of the servants, maybe. We’ve got a Papuan woman here who’s ill: in fact, she’s a little mad, and we’re moving her to-morrow. I’ll go and see if you like?” He looked toward Michael as though seeking permission. His whole attitude was one of humility, and Michael required no more than the sight of that pallid face and those chattering teeth to turn his suspicion to certainty. Something was happening in this house that he must get to the bottom of. “May I go and see?” asked Penne. Michael nodded. The stout man shuffled out of the room as though he were in a hurry to be gone, and the lock clicked. Instantly Michael was at the door, turned the handle and pulled. It was locked! He looked round the room quickly, and, running to one of the windows, flung back the curtain and pulled at the shutter. But this, too, was locked. It was, to all intents and purposes, a door with a little keyhole at the bottom. He was examining this when all the lights in the room went out, the only illumination being a faint red glow from the fire. CHAPTER XIII THE TRAP THAT FAILED AND then Michael heard a faint creak in one corner of the room. It was followed by the almost imperceptible sound of bare feet on the thick pile carpet, and the noise of quick breathing. He did not hesitate. Feeling again for the keyhole of the shutter, he pulled out his pistol and fired twice at the lock. The sound of the explosion was deafening in the confined space of the room. It must have had an electrical effect upon the intruder, for when, with a wrench, the shutter opened, and at a touch the white blind sprang up, flooding with light the big, ornate room, it was empty.
