She drove herself to the police station, and was taken at once to the somewhat comfortless office where Hannasyde was going through a pile of documents.
He got up as she came in, and favoured her with a rather keen look. "Good-afternoon, Mrs. North. Will you sit down?"
She took a chair on the side of the desk opposite to him. "Thank you. Do you know, the only time I've ever been to a police station before was about a dog I once lost?"
"Indeed?" he said. "What is it you wish to say to me, Mrs. North?"
She raised her eyes to his face. "I want to tell you something which I ought to have told you this morning," she said frankly.
"Yes?"
His voice betrayed nothing but a kind of polite interest. She found it a little disconcerting, and stumbled over her next words. "It was silly of me, but you know how it is when one is suddenly confronted - or no, perhaps you don't. It's always you who - who asks the questions, isn't it?"
"I have had plenty of experience of people who either concealed the truth, or told me only a part of it, if that is what you mean, Mrs. North."
"I suppose it is," she admitted. "Perhaps you can understand, though, how awkward it was for me, when you - well, exposed my - my indiscretions this morning. I won't attempt to deny that I was badly rattled, not because of the murder, because I had nothing to do with that, but because I'm not the sort of woman my dealings with Mr. Fletcher might have led you to suppose, and - and there could be nothing worse from my point of view than to have an indiscretion - like that - made public. The only idea in my head this morning was to admit as little as I need. You - you do understand that, don't you?"
He nodded. "Perfectly, Mrs. North. Please go on!"
"Yes. Well, since I saw you I've had time to think it over, and of course I realise that when it's a question of murder it would be terribly wrong of me to keep anything back. Moreover -' she smiled shyly across at him -'you were so very nice about it, not - not giving me away to my husband, that I feel sure I can trust you."
"I had better make it clear, Mrs. North, that while I have not the smallest desire to create any unnecessary unpleasantness in connection with this case, my consideration for your feelings cannot interfere with the execution of what I may decide to be my duty."
"Of course not; I quite appreciate that."
He looked at her. A few hours earlier she had been nervous to the point of distraction, but she had herself well in hand now. She met his eyes deprecatingly, but quite squarely, and was sure enough of herself to employ little feminine tricks to beguile him. She was a lovely woman; he wondered what the brain behind her soft blue eyes was evolving. She was probably playing a part, but so well that he could not be sure of it. It was easy to believe that she had concealed some of the truth earlier in the day; the reasons she put forward for having done so were quite credible; but it would not be so easy to know how much of whatever revelations were to come was to be believed.
He said impersonally: "Well, Mrs. North? What is it that you are going to tell me?"
"It is about what happened after I hid behind that bush, outside Mr. Fletcher's study. I said that as soon as the man who came up the path had entered the house I went away. Actually, I didn't go away."
His keen eyes narrowed slightly. "Indeed! Why not?"
She began to fidget a little with the clasp of her handbag. "You see, what I originally said about my interview with Mr. Fletcher wasn't true. It - it wasn't amicable. At least, not on my part. Mr. Fletcher, as you suggested this morning, Superintendent, did want something from me which I - which I was more than unwilling to give. I don't want to give you a false impression. Looking back, I feel sure I lost my head over the whole affair, and - and perhaps exaggerated things. Mr. Fletcher was using my IOUs against me, but in a playful sort of way. I expect it was only a bluff, for really he wasn't a bit like that. Only I was frightened, and behaved stupidly. I went round to his house that evening to try to persuade him to give me back my notes. Something he said made me lose my temper, and I walked out of the house in a rage. But while I was hiding behind the bush I realised that losing my temper wasn't going to help me. I thought perhaps I ought to have another shot at coaxing the notes out of Mr. Fletcher, though at the same time I rather dreaded the idea of going back into that room."
"Just a moment!" Hannasyde interrupted. "What happened in the study while you were hiding behind the bush?"
"I don't know. You remember I told you that I thought the man I saw closed the window? Well, that was true. I only heard a confused murmur of voices. I don't think he was in the room for more than six or seven minutes. It seemed longer to me, but it can't have been, because the clock in the hall began to strike ten when I finally left the house. But I haven't got to that yet. While I was still waiting, and not knowing quite what I ought to do next, the window of the study was pushed open, and both Mr. Fletcher and the other man came out. Mr. Fletcher had a light, carrying voice, and I distinctly heard him say: "A little mistake on your part. Permit me to show you the way out!"'
"And the other? Did he speak?"
"Not in my hearing. Mr. Fletcher said something else, but I couldn't catch what it was."
"Did he appear to be at all put-out?"
"No, but he was the sort of man who never showed when he was annoyed. He sounded rather mocking, I thought. I don't think there can have been a quarrel, because he just strolled down the path with the other man quite casually, not hurrying, or anything. In fact, I rather thought that perhaps the man had walked in by mistake."
"Oh! And then?"
"Well, you know that the path to the gate twists past some bushes? As soon as they had reached the bend, I slipped from behind the bush, and ran back to the study. I - I had a wild sort of hope that my notes might be in Mr. Fletcher's desk, and it seemed to me that here was my chance to get hold of them. Most of the drawers were unlocked, and I didn't bother about them. But the centre drawer had its key in it, and I happened to know that Mr. Fletcher used to keep it locked. I've seen him take the key out of his pocket to open it. I pulled it out, but I couldn't see my notes. Then I heard Mr. Fletcher coming up the path: he was whistling. I got a sudden panic, and instead of staying where I was I shut the drawer, and whisked myself over to the door. I just had time to open it very gingerly to make sure that no one was in the hall, before escaping that way. There wasn't anyone in sight, and I slipped into the hall before Mr. Fletcher had reached the study. That was when the clock began to strike. As a matter of fact, it gave me a dreadful start, because it's one of those tall-case clocks that make a whirring noise before they begin striking. I
walked down the hall to the front door, let myself out as quietly as I could, and went home by way of Vale Avenue, which, I expect you know, cuts across the top of my own road."
There was a short silence after she had finished speaking. Hannasyde moved a paper slightly on his desk. "Mrs. North, why have you told me this?" he asked.
"But - but isn't it obvious?" she said. "I couldn't let you think that a perfectly innocent man might have murdered Mr. Fletcher! You see, I know that Mr. Fletcher was alive when that man left the house."
"How long were you in the study, the second time?" he asked.
"I don't know, but not more than three minutes. Oh, less! I had only time to look hurriedly through that drawer before I heard Mr. Fletcher coming back."
"I see."
Something in his voice made her stiffen. "You don't believe me? But it's true: I can prove it's true!"
"Can you? How?"
She spread out her hands. "I wasn't wearing gloves. My finger-prints must have been on the door. Look, I'll show you!" She got up, and moved to the door, clasping the handle in her right hand, and laying her left hand on the panel above it. "You know how one eases a door open, if one's afraid of its making any noise? I remember putting my left hand on it, just like this."
