“What is the meaning of this new outrage?” he demanded coldly. “Is it your prerogative to force a citizen to leave his private affairs in order to be bullied?”

“It’s my duty to bring murderers to justice,” replied Markham, with equal coldness. “And if any citizen considers that giving aid to the authorities is an outrage, that’s his prerogative. If you have anything to fear by answering my questions, doctor, you are entitled to have your attorney present. Would you care to phone him to come here now and give you legal protection?”

Doctor Lindquist hesitated. “I need no legal protection, sir. Will you be good enough to tell me at once why I was brought here?”

“Certainly; to explain a few points which have been discovered regarding your relationship with Miss Odell, and to elucidate—if you care to—your reasons for deceiving me, at our last conference, in regard to that relationship.”

“You have, I infer, been prying unwarrantably into my private affairs. I had heard that such practices were once common in Russia. . . .”

“If the prying was unwarranted, you can, Doctor Lindquist, easily convince me on that point; and whatever we may have learned concerning you will be instantly forgotten.—It is true, is it not, that your interest in Miss Odell went somewhat beyond mere paternal affection?”

“Are not even a man’s sacred sentiments respected by the police of this country?” There was insolent scorn in the doctor’s tone.

“Under some conditions, yes; under others, no.” Markham controlled his fury admirably. “You need not answer me, of course; but, if you choose to be frank, you may possibly save yourself the humiliation of being questioned publicly by the People’s attorney in a court of law.”

Doctor Lindquist winced and considered the matter at some length.

“And if I admit that my affection for Miss Odell was other than paternal—what then?”
