"I should make it easy for him, Miss Hawkins, if I was in your place. Let the old gentleman please himself." Thus the officer, whose sedateness of manner acts beneficially. She accepts the suggestion, standing back from her father with a stupid, bewildered gaze, between him and the exit to the roof. "Give him time," says Sub-Inspector Cardwell. He takes the time, and his speech dies down. But he can move that hand better now--may make its action serve for speech. Slowly he raises it and points--points straight at his daughter. He wants her help--is that it? She thinks so, but when she acts on the impulse he repels her, feebly shouting out: "No--no--no!" "Come out from between him and the clock, missis," says the officer, thinking he has caught a word right, and that a clock near the door is what the old man points at. "He thinks it's six o'clock." But the word was not _six_. The daughter moves aside, and yet the finger points. "It's nowhere near six, father dear!" she says. "Not one o'clock yet!" But still the finger points. And now a wave of clearer articulation overcomes a sibilant that has been the worst enemy of speech, and leaves the tongue free. "Wix!" That's the word. "Got it!" exclaims the officer, and the woman with a shriek falls insensible. He takes little notice of her, but whistles for his mate below--a peculiar whistle. It brings the man who was keeping watch in the lane. "Got him all right," says his principal. "Out here on the tiles. That's your meaning, I take it, Mr. Hawkins?" The old man nods repeatedly. "And he's took the key out with him and locked to the door. That's it, is it?" More nods, and then the officer mounts the short ladder and knocks hard upon the door. He speaks to the silence on the other side. "You've been seen, Mr. Wix. It's a pity to spoil a good lock. You've got the key. We can wait a bit. Don't hurry!" Footsteps on the roof, and a shout from the garden below! He is seen now--no doubt of it--whatever he was before. What is that they are calling from the garden? "He's got a loose tile. Look out!" "Don't give him a chance to aim with it," says Jacomb below to his chief on the ladder. Who replies:--"He's bound to get half a chance. Keep your eyes open!" A thing to be done, certainly, with that key sounding in the lock. The officer Cardwell only waited to hear it turn to throw his full weight on the door, which opened outwards. He scarcely waited for the back-click to show that the door, which had no hasp or clutch beyond the key-service, was free on its hinges. Nevertheless, he was not so quick but that the man beyond was quicker, springing back sharp on the turn of his own hand. Cardwell stumbled as the door gave, unexpectedly easily, and nearly fell his length on the leads.
