"Well, say, this begins to look like the goods," cried Miss Molloy gleefully. "If this fellow has a cut thumb _and_ a cold in the head, there's nothing to it. It's all over except tearing off the false whiskers and saying 'I am Hawkshaw, the Detective!' Say, listen. You get that little car of yours out and you and I will go right over to Healthward Ho, now. You see, if I come along that'll make him all the more unsuspicious. We'll tell him I'm a girl with a brother that's been whooping it up a little too heavily for some time past, and I want to make inquiries with the idea of putting him where he can't get the stuff for a while. I'm sure you're on the right track. This bird Twist is the villain of the piece, I'll bet a million dollars. As you say, a fellow that wanted to burgle houses in these parts just naturally would settle down and pretend to be something respectable. You go and get that car out, Mr. Carroll, and we'll be off right away." John reflected. Filled though he was with the enthusiasm of the chase, he could not forget that his time to-day was ear-marked for other and higher things than the investigation of the mysterious Doctor Twist, of Healthward Ho. "I must be back here by a quarter to one," he said. "Why?" "I must." "Well, that's all right. We're not going to spend the week end with this guy. We're simply going to take a look at him. As soon as we've done that, we come right home and turn the thing over to the police. It's only twenty miles. You'll be back here again before twelve." "Of course," said John. "You're perfectly right. I'll have the car out in a couple of minutes." He hurried off. His views concerning Miss Molloy now were definitely favourable. She might not be the sort of girl he could ever like, she might not be the sort of girl he wanted staying at the Hall, but it was idle to deny that she had her redeeming qualities. About her intelligence, for instance, there was, he felt, no doubt whatsoever. And yet it was with regard to this intelligence that Soapy Molloy was at this very moment entertaining doubts of the gravest kind. His eyes were protruding a little, and he uttered an odd, strangled sound. "It's all right, you poor sap," said Dolly, meeting his shocked gaze with a confident unconcern. Soapy found speech. "All right? You say it's all right? How's it all right? If you hadn't pulled all that stuff...." "Say, listen!" said Dolly urgently. "Where's your sense? He would have gone over to see Chimp anyway, wouldn't he? Nothing we could have done would have headed him off that, would it? And he'd noticed Chimp had a cut finger, without my telling him, wouldn't he? All I've done is to make him think I'm on the level and working in cahoots with him." "What's the use of that?" "I'll tell you what use it is. I know what I'm doing. Listen, Soapy, you just race into the house and get those knock-out drops and give them to me. And make it snappy," said Dolly.
