"As well that as anything," muttered its proprietor. "By the way, you might get testimonials from any of 'em that get well. Can you find O'Farrell?" "Yes, sir." "Tell him I want to see him at my office at two o'clock." "Ver' good. What do you think it is, Doctor?" Dr. Surtaine waved a profound hand. "Very obscure. Demands consideration. But get those cases out of the city. There's no occasion to risk the Board of Health seeing them." At the corner Dr. Surtaine again met Miss Elliot and stopped her. "My dear young lady, ought you to be risking your safety in such places as these?" "No one ever interferes. My badge protects me." "But there's so much sickness." "That is what brings me," she smiled. "It might be contagious. In fact, I have reason to believe that there is--er--measles in this block." "I've had it, thank you. May I give you a lift in my car?" "No, thank you. But I think you should consult your uncle before coming here again." "The entire Surtaine family seems set upon barring me from the Rookeries. I wonder why." With which parting shot she left him. Going home, he bathed and changed into his customary garb of smooth black, to which his rotund placidity of bearing imparted an indescribably silky finish. His discarded clothes he put, with his own hands, into an old grip, sprinkled them plenteously with a powerful disinfectant, and left orders that they be destroyed. It was a phase of Dr. Surtaine's courage that he never took useless risks, either with his own life, or (outside of business) with the lives of others. Having lunched, he went to his office where he found O'Farrell waiting. The politician greeted him with a mixture of deference and familiarity. At one stage of their acquaintance familiarity had predominated, when having put through a petty but particularly rancid steal for the benefit of the Certina business, O'Farrell had become inspired with effusiveness to the extent of addressing his patron as "Doc." He never made that particular error again. Yet, to the credit of Dr. Surtaine's tact and knowledge of character be it said, O'Farrell was still the older man's loyal though more humble friend, after the incident. To-day he was plainly apprehensive. "Them other cases the same thing?" he asked. "Yes, O'Farrell." "What is it?" "That I can't tell you." "You went in and saw 'em?" Dr. Surtaine nodded. "By God, I wouldn't do it," declared O'Farrell, shivering. "I wouldn't go in there, not to collect the rent! It's catching, ain't it?" "In all probability it is a contagious or zymotic disease." The politician shook his head, much impressed, as it was intended he should be. "Cleaning-up time for you, I guess, O'Farrell," pursued the other. "All right, if you say so. But I won't have any Board o' Health snitches bossing it. They'd want to pull the whole row down." "Exactly what ought to be done."
