The hound went towards the ruin and Sir Lancelot followed. The wall was broken down in many places, and the path all overgrown and weedy, and as he came to the courtyard before the house, he saw the fishponds choked with weeds and the horseblock green with moss, and in the great doorway grew charnel and hellebore, and the spiked hemlock waved and spilt its seed in the wind. The windows hung by their hinges, and the green moss crept down the wide wet cracks in the walls.

But the dog ran over the drawbridge into the house, and Sir Lancelot gat from his horse and tethered it to the post beside the horseblock, and so went across the bridge, which was full sodden and worm-eaten, and bent beneath his weight.

Coming into a great hall, foul with many rotting leaves, he saw a table in the midst thereof, and on it was a knight that was a seemly man, and he lay as if he were dead, and the black hound licked his wound. And by his side there was a lovely lady, who started up, weeping and wringing her hands, and she said:

'O knight, too much evil have you brought to me!'

'Why say ye so?' said Sir Lancelot; 'I never did harm to this knight, for hither did this hound lead me, and therefore, fair lady, be not displeased with me, for grief is upon me for your sorrow and your sadness.'

'Truly, sir,' said the lady, and she laid her face in her hands and sobbed full sorely, so that Sir Lancelot was much stirred thereat, 'I trow, as ye say it, that you are not the knight that hath near slain my love and my husband. And never may he be healed of his deadly wound except some good knight aid me. But he must be so bold and valiant a man, that never, I think, may I find such a one in the little time I have before my dear lord shall die!'

'Now on the honour of my knighthood,' replied Sir Lancelot, 'I do not presume that I am such a one as you desire; but if I may aid you and ease your sorrow, that would I do most willingly. What is it I should do?'

'Oh, sir knight!' cried the lady, and her lovely eyes looked full thankfully at Sir Lancelot, 'if ye would, it were the greatest deed you have ever done, however bold a knight ye may be. For this my lord is sore wounded by a knight whom he met in the forest this day, and by one thing only may he be made whole. For there is a lady, a sorceress, that dwelleth in a castle here beside, and she hath told me that my husband's wounds may never be whole till I may find a knight that would go at midnight into the Chapel Perilous beside the Mere, and that therein he should find before the high altar a sword, and the shroud in which the dead wizard-knight is lapped, and with that sword my husband's wounds should be searched, and a piece of the shroud should bind them.'

'This is a marvellous thing,' said Sir Lancelot, 'and I will essay it. But what is your husband's name?'

'Sir,' she said, 'his name is Sir Meliot de Logres.'
