with Ralph Cornboise.
âSit down, Mr. Cornboise,â said Crisp.
âI am under your orders.â Ralph sat down. âBut I shall not answer any more questions.â
âThen you can listen. In your confession you state that you left the library at five fifteen after killing your uncle. Your statement as to time has been confirmed by two independent witnesses, one of whom is Mr. Querk.â
âYou have discovered that I am not a liar! Congratulations, Colonel!â
Crisp turned to Querk.
âMr. Querk, did you enter the library after you had seen Mr. Cornboise leave it?â As Querk assented. âDid you then have a conversation with Lord Watlington lasting until approximately five thirty?â
âI did, Chief Constable.â
Ralph sprang from his chair. Crisp motioned him to silence.
Querk seized the opportunity to go on talking.
âBut surely my friend, Mr. Cornboise, does not maintain that he did this dreadful deed before five thirty?â
âWhatâs the good, Querk!â groaned Ralph. âI know you think itâs kind of youâit is kind! But theyâll prove youâre only trying to save me. And I donât even want to be saved!â
âRalph! You want us to believe that you killed your uncle? Before five fifteen? Come, my dear boy!â
Exasperated, Ralph dropped back in his chair without answering.
âHe does believe it, Chief Constable!â exclaimed Querk. âIt is the clearest possible case of hallucination. He can even persuade himself that I am telling a deliberate falsehood.â
âOh, shut up, Querk!â snapped Ralph. âItâs no good, I tell you!â
âYou observe,â said Querk with triumph, âhow irritably he addressesâerâmyself. Because I am menacing the hallucination. There can be no question whatever of my friendâs sincerity. I gladly pardon his brusquerie. Such cases are well authenticated. The patient first wishes he had killed a given person. I grieve to admit that he wishes he had killed his uncle, but before all else, Chief Constable, we must be realistic. The patientââ
A snort of ill-temper came from Ralph.
âCanât you let me off this, Colonel? Iâve saved you a lot of troubleâyou might treat me decently!â
âThe patient,â boomed Querk, âbecomes terrified of his own wishâit is his secret fear of himself that gives the nightmare the semblance of reality.â
âIâm not a patient, damn you!â shouted Ralph.
So far the process of shaking them up together had yielded little but noise. Crisp decided to give it direction.
âCornboise, wouldnât you like to ask Mr. Querk a few questions?â
âAbout that psychological nonsense? No thanks. Iâve had a bellyfull of the subconscious fromâothers. Iâll ask you a question, Chief Constable. I happen to know as well as you do that a doctor can tell how long a chapâs been dead. What time did my uncle die?â
For a second only, Crisp hesitated.
âBetween five and five thirty,â he said.
âChief Constable! â gasped Querk.
âThere you are, Querk!â Ralph laughed contemptuously. âIf you prove I didnât do it, you prove you did.â
Querk constructed a smileâthe smile that suffocates opponents with understanding and forgiveness.
âI think, my dear boy, that I can safely leave the Chief Constable to deal with that little dilemma!â
There fell a short, intense silence.
âI donât know the answer,â said Crisp.
With tolerance, with dignity, the saintlike smile faded. Querk coughed, gave a little deprecatory laugh. âCan it be, Chief Constable, that you think it is I who am suffering from hallucination? That Mr. Cornboise did indeed kill poor Lord Watlington?â
âI donât believe youâre suffering from hallucination,â answered Crisp. âAnd I
