'The next point,' I said, 'will be for us to prove it.'

At that moment the bell rang, and one of the house-servants—all puzzled by this conflict of interests—came in with a telegram, which he handed me on a salver. I broke it open, without glancing at the envelope. Its contents baffled me: 'My address is Hotel Bristol, Paris; name as usual. Send me a thousand pounds on account at once. I can't afford to wait. No shillyshallying.'

The message was unsigned. For a moment, I couldn't imagine who sent it, or what it was driving at.

Then I took up the envelope. 'Viscount Southminster, 24 Park Lane North, London.'

My heart gave a jump. I saw in a second that chance, or Providence, had delivered the conspirators into my hands that day. The telegram was from Higginson! I had opened it by accident.

It was obvious what had happened. Lord Southminster must have written to him on the result of the trial, and told him he meant to take possession of his uncle's house immediately. Higginson had acted on that hint, and addressed his telegram where he thought it likely Lord Southminster would receive it earliest. I had opened it in error, and that, too, was fortunate, for even in dealing with such a pack of scoundrels, it would never have occurred to me to violate somebody else's correspondence had I not thought it was addressed to me. But having arrived at the truth thus unintentionally, I had, of course, no scruples about making full use of my information.

I showed the despatch at once to Lady Georgina and Mr. Hayes. They recognised its importance. 'What next?' I inquired. 'Time presses. At half-past three Harold comes up for examination at Bow Street.'

Mr. Hayes was ready with an apt expedient. 'Ring the bell for Mr. Ashurst's valet,' he said, quietly. 'The moment has now arrived when we can begin to set these conspirators by the ears. As soon as they learn that we know all, they will be eager to inform upon one another.'

I rang the bell. 'Send up White,' I said. 'We wish to speak to him.'

The valet stole up, self-accused, a timid, servile creature, rubbing his hands nervously, and suspecting mischief. He was a rat in trouble. He had thin brown hair, neatly brushed and plastered down, so as to make it look still thinner, and his face was the average narrow cunning face of the dishonest man-servant. It had an ounce of wile in it to a pound or two of servility. He seemed just the sort of rogue meanly to join in an underhand conspiracy, and then meanly to back out of it. You could read at a glance that his principle in life was to save his own bacon.
