Poirot investigates - Agatha Christie [59]
‘What does he himself say to that?’
‘Denied first of all that he had ever left the study. But the maid was positive, and he pretended afterwards that he had forgotten just stepping out of the window to examine an unusual species of rose. Rather a weak story! And there’s fresh evidence against him come to light. Mr Davenheim always wore a thick gold ring set with a solitaire diamond on the little finger of his right hand. Well, that ring was pawned in London on Saturday night by a man called Billy Kellett! He’s already known to the police–did three months last autumn for lifting an old gentleman’s watch. It seems he tried to pawn the ring at no less than five different places, succeeded at the last one, got gloriously drunk on the proceeds, assaulted a policeman, and was run in in consequence. I went to Bow Street with Miller and saw him. He’s sober enough now, and I don’t mind admitting we pretty well frightened the life out of him, hinting he might be charged with murder. This is his yarn, and a very queer one it is.
‘He was at Entfield races on Saturday, though I dare say scarfpins was his line of business, rather than betting. Anyway, he had a bad day, and was down on his luck. He was tramping along the road to Chingside, and sat down in a ditch to rest just before he got into the village. A few minutes later he noticed a man coming along the road to the village, “dark-complexioned gent, with a big moustache, one of them city toffs,” is his description of the man.
‘Kellett was half concealed from the road by a heap of stones. Just before he got abreast of him, the man looked quickly up and down the road, and seeing it apparently deserted he took a small object from his pocket and threw it over the hedge. Then he went on towards the station. Now, the object he had thrown over the hedge had fallen with a slight “chink” which aroused the curiosity of the human derelict in the ditch. He investigated and, after a short search, discovered the ring! That is Kellett’s story. It’s only fair to say that Lowen denies it utterly, and of course the word of a man like Kellett can’t be relied upon in the slightest. It’s within the bounds of possibility that he met Davenheim in the lane and robbed and murdered him.’
Poirot shook his head.
‘Very improbable, mon ami. He had no means of disposing of the body. It would have been found by now. Secondly, the open way in which he pawned the ring makes it unlikely that he did murder to get it. Thirdly, your sneak-thief is rarely a murderer. Fourthly, as he has been in prison since Saturday, it would be too much of a coincidence that he is able to give so accurate a description of Lowen.’
Japp nodded. ‘I don’t say you’re not right. But all the same, you won’t get a jury to take much note of a jailbird’s evidence. What seems odd to me is that Lowen couldn’t find a cleverer way of disposing of the ring.’
Poirot shrugged his shoulders. ‘Well, after all, if it were found in the neighbourhood, it might be argued that Davenheim himself had dropped it.’
‘But why remove it from the body at all?’ I cried.
‘There might be a reason for that,’ said Japp. ‘Do you know that just beyond the lake, a little gate leads out on to the hill, and not three minutes’ walk brings you to–what do you think?–a lime kiln.’
‘Good heavens!’ I cried. ‘You mean that the lime which destroyed the body would be powerless to affect the metal of the ring?’
‘Exactly.’
‘It seems to me,’ I said, ‘that that explains everything. What a horrible crime!’
By common consent we both turned and looked at Poirot. He seemed lost in reflection, his brow knitted, as though with some supreme mental effort. I felt at last his keen intellect was asserting itself. What would his first words be? We were not long left in doubt. With a sigh, the tension of his attitude relaxed and turning to Japp, he asked:
‘Have you any idea, my friend, whether Mr and Mrs Davenheim occupied the same bedroom?’
The question seemed so ludicrously inappropriate that for a moment we both stared in silence.
