'With a lawyer's eye. Mine is that of an investigator,' said Miller. 'And I knew what I was looking for. So I did not start with the house, but with the outbuildings. Are you aware that Mr Hanson had an extremely well-equipped carpentry workshop in a former barn behind the stables?'
'Certainly,' said Pound. 'It was his hobby.'
'Precisely,' said Miller. 'And it was here I concentrated my efforts. The place had been scrupulously cleaned; vacuum-cleaned.'
'Possibly by Richards, the chauffeur/handyman,' said Pound.
'Possibly, but probably not. Despite the cleaning, I observed stains on the floorboards and had some splinters analysed. Diesel fuel. Pursuing a hunch, I thought of some kind of machine, an engine perhaps. It's small enough market and I found the answer within a week. Last May Mr Hanson bought a powerful diesel-fuelled electric generator and installed it in his workshop. He disposed of it for scrap just before he died.'
'To operate his power tools, no doubt,' said Pound.
'No, the ring main was strong enough for that. To operate something else. Something that needed enormous power. In another week I had traced that too. A small, modern and very efficient furnace. It too is long gone, and I have no doubt the ladles, asbestos gloves and tongs have been dumped at the bottom of some lake or river. But, I think I may say I was a little more thorough than Mr Hanson. Between two floorboards, jammed out of sight and covered by compacted sawdust, no doubt just where it had fallen during his operations, I discovered this.'
It was his
'I have had it analysed of course. It is high-grade 99.95 per cent pure platinum.'
'You have traced the rest?' whispered Mrs Armitage.
'Not yet, madam, but I shall. Have no fear. You see Mr Hanson made one great mistake in selecting platinum. It has one property that he must have underestimated and yet which is quite unique. Its weight. Now at least we know what we are looking for. A wooden crate of some kind, apparently innocent to look at, but — and this is the point — weighing just under half a ton…
Mrs Armitage threw back her head and uttered a strange raucous cry like the howl of a wounded animal. Miller jumped a foot. Mr Armitage dropped his head forward into his hands. Tarquin Armitage rose to his feet, his spotty complexion brick red with rage, and screamed, 'That bloody bastard.'
Martin Pound stared unbelievingly at the startled private investigator. 'Good Lord,' he said. 'Oh, my goodness me. He actually took it with him.'
Two days later Mr Pound informed the Inland Revenue of the full facts of the case. They checked the facts and, albeit with an ill grace, declined to pursue.
Barney Smee walked happily and with a brisk pace towards his bank, confident he would just get there before they closed for the Christmas holiday. The reason for his pleasure was tucked inside his breast pocket: a cheque for a quite substantial sum, but only the last of a series of such cheques that over the past few months had ensured him a much higher income than he had ever managed to earn in twenty years in the risky business of dealing in scrap metals for the jewellery industry.
He had been right, he congratulated himself, to take the risk, and it had undeniably been a high one. Still, everyone was in the tax-dodging business nowadays and who was he to condemn the source of good fortune simply because the man had wished to deal only in cash? Barney Smee had no difficulty in understanding the silver-haired investor who called himself Richards and had a driving licence to prove it. The man evidently had bought his 50-ounce ingots years before, when they were cheap. To have sold them on the open market through Johnson Matthey would beyond doubt have secured him a higher price, but at what cost in capital gains tax? Only he could have known and Barney Smee was not one to probe.
In any case, the whole trade was rife with cash deals. The ingots had been genuine; they even bore the original assay mark of Johnson Matthey, from whom they had once come. Only the serial number had been blazed out. That had cost the old man a lot, because without the serial number Smee could not offer him anything near fair market price. He could only offer scrap price, or producer's price, about 440 US dollars an ounce. But then, the serial numbers would have identified the owner to the Inland Revenue, so maybe the old man knew his onions after all.
