We turned next to the signatures. The principal one was clearly Mr. Ashurst's— I knew it at once—his legible fat hand, 'Marmaduke Courtney Ashurst.' And then the witnesses? They fairly took our breath away.

'Why, Higginson's sister isn't one of them at all,' Mr. Hayes cried, astonished.

A flush of remorse came over me. I saw it all now. I had misjudged that poor woman! She had the misfortune to be a rogue's sister, but, as Harold had said, was herself a most respectable and blameless person. Higginson must have forged her name to the document; that was all; and she had naturally sworn that she never signed it. He knew her honesty. It was a master-stroke of rascality.

'The other one isn't here, either,' I exclaimed, growing more puzzled. 'The waiter at the hotel! Why, that's another forgery! Higginson must have waited till the man was safely dead, and then used him similarly. It was all very clever. Now, who are these people who really witnessed it?'

'The first one,' Mr. Hayes said, examining the handwriting, 'is Sir Roger Bland, the Dorsetshire baronet: he's dead, poor fellow; but he was at Florence at the time, and I can answer for his signature. He was a client of mine, and died at Mentone. The second is Captain Richards, of the Mounted Police: he's living still, but he's away in South Africa.'

'Then they risked his turning up?'

'If they knew who the real witnesses were at all—which is doubtful. You see, as you say, they may have seen the rough draft only.'

'Higginson would know,' I answered. 'He was with Mr. Ashurst at Florence at the time, and he would take good care to keep a watch upon his movements. In my belief, it was he who suggested this whole plot to Lord Southminster.'

'Of course it was,' Lady Georgina put in. 'That's absolutely certain. Bertie's a rogue as well as a fool: but he's too great a fool to invent a clever roguery, and too great a knave not to join in it foolishly when anybody else takes the pains to invent it.'

'And it was a clever roguery,' Mr. Hayes interposed. 'An ordinary rascal would have forged a later will in Lord Southminster's favour and run the risk of detection; Higginson had the acuteness to forge a will exactly like the real one, and to let your husband bear the burden of the forgery. It was as sagacious as it was ruthless.'
