stabbed just because the dagger happened to be lying on the table in front of us. It was a mere coincidence that Lady Dwighton should have brought it down with her.â
âWas it?â asked Mr Quin.
âNow if theyâd only confined themselves to saying that theyâd killed Sir James, without particularizing how ââ went on Mr Satterthwaite â âwhat would have been the result?â
âThey might have been believed,â said Mr Quin with an odd smile.
âThe whole thing was exactly like a novel,â said the colonel.
âThatâs where they got the idea from, I daresay,â said Mr Quin.
âPossibly,â agreed Mr Satterthwaite. âThings one has read do come back to one in the oddest way.â He looked across at Mr Quin. âOf course,â he said, âthe clock really looked suspicious from the first. One ought never to forget how easy it is to put the hands of a clock or watch forward or back.â
Mr Quin nodded and repeated the words. âForward,â he said, and paused. âOr back.â
There was something encouraging in his voice. His bright, dark eyes were fixed on Mr Satterthwaite.
âThe hands of the clock were put forward,â said Mr Satterthwaite. âWe know that.â
âWere they?â asked Mr Quin.
Mr Satterthwaite stared at him. âDo you mean,â he said slowly, âthat it was the watch which was put back? But that doesnât make sense. Itâs impossible.â
âNot impossible,â murmured Mr Quin.
âWell â absurd. To whose advantage could that be?â
âOnly, I suppose, to someone who had an alibi for that time.â
âBy gad!â cried the colonel. âThatâs the time young Delangua said he was talking to the keeper.â
âHe told us that very particularly,â said Mr Satterthwaite.
They looked at each other. They had an uneasy feeling as of solid ground failing beneath their feet. Facts went spinning round, turning new and unexpected faces. And in the centre of the kaleidoscope was the dark, smiling face of Mr Quin.
âBut in that case ââ began Melrose ââ in that case ââ
Mr Satterthwaite, nimble-witted, finished his sentence for him. âItâs all the other way round. A plant just the same â but a plant against the valet. Oh, but it canât be! Itâs impossible. Why each of them accused themselves of the crime.â
âYes,â said Mr Quin. âUp till then you suspected them, didnât you?â His voice went on, placid and dreamy. âJust like something out of a book, you said, colonel. They got the idea there. Itâs what the innocent hero and heroine do. Of course it made you think them innocent â there was the force of tradition behind them. Mr Satterthwaite has been saying all along it was like something on the stage. You were both right. It wasnât real. Youâve been saying so all along without knowing what you were saying. Theyâd have told a much better story than that if theyâd wanted to be believed.â
The two men looked at him helplessly.
âIt would be clever,â said Mr Satterthwaite slowly. âIt would be diabolically clever. And Iâve thought of something else. The butler said he went in at seven to shut the windows â so he must have expected them to be open.â
âThatâs the way Delangua came in,â said Mr Quin. âHe killed Sir James with one blow, and he and she together did what they had to do ââ
He looked at Mr Satterthwaite, encouraging him to reconstruct the scene. He did so, hesitatingly.
âThey smashed the clock and put it on its side. Yes. They altered the watch and smashed it. Then he went out of the window, and she fastened it after him. But thereâs one thing I donât see. Why bother with the watch at all? Why not simply put back the hands
