The House of the Red Slayer

friar exclaimed, ‘I want the key to Sir Ralph’s chamber!‘
    Athelstan took one of the keys from its hook and went halfway back up the stairs, shook his head and came down.
    ‘On second thoughts,’ he said, ‘let us send for Master Colebrooke.’ He handed the key back to the soldier. ‘Tell me,’ the friar asked, ‘did I take any longer than young Geoffrey?’
    ‘No, about the same. He was a little longer in the passageway, but not much.‘
    Sir Fulke pushed his way forward. ‘What does this all mean?’ he demanded.
    Athelstan smiled. ‘Now I will show you. Master Lieutenant, re-open the door at the top of the stairs and let us all go up.’
    The lieutenant ran to re-open the door and they all followed him down the cold, vaulted passageway. Colebrooke unlocked Whitton’s chamber and they followed him in. Sir Fulke promptly cursed. Philippa gave a short scream. The chamber was icy cold, the shutters wide open, and the bolster on the dirty, grey mattress of the four-poster bed had been savagely slashed, the goose feathers trickling out in grisly reminder of Sir Ralph’s murder.
    ‘Who did this? What evil nonsense is this?’ Hammond the chaplain spoke up.
    Athelstan ignored him and confronted Parchmeiner.
    ‘You know what I have done,’ he said quietly. ‘Exactly what you did on the morning you murdered Sir Ralph, and I’ll tell you how. First, when Sir Ralph moved to the North Bastion, you acted the role of the obsequious future son-in-law. You helped him move a few possessions across. You see, the chamber was guarded when Sir Ralph moved in but not before, so you carefully oiled the hinges and the lock of the door which explains the oil stains in the corridor outside. Secondly, the floor above is sealed off, and at the far end of the corridor outside is a pile of fallen masonry. You hid a dagger there amongst the rubble, as I asked Colebrooke to conceal Sir John’s. After I slashed the bolster, I hid the dagger there again. On the night before Sir Ralph died, you sat with him at table. You helped him to drink deeply, aided probably by a fairly strong sleeping potion, enough to make him drowsy. Thirdly, you helped Sir Ralph to the foot of the steps, the guards took him up to his chamber, and it is probably then that you exchanged the keys. You took the one Sir Ralph left there for the use of the guards and slipped another on to the hook. I asked Colebrooke to do the same. He handed the real key to me when we were in Mistress Philippa’s chamber.’ Athelstan paused. ‘The next morning you come across, the guards search you, but you have nothing except your own harmless possessions which,’ Athelstan touched the young man’s side carefully, ‘like any merchant, include a ring of keys. You climb the steps, the guards let you through, and you proceed to Sir Ralph’s chamber. As you knock and shout, you open the door silently because the lock hinges are so well oiled. The rest was easy.’
    ‘But-’ Colebrooke intervened.
    ‘Not yet,’ Athelstan snapped back. He studied Parchmeiner’s eyes carelully. ‘Once inside, you move very quickly. The shutters are unlatched, the cold air streams in. You cross to Whitton’s bed and yank his head back. Sir Ralph, still in a heavy stupor, may have opened his eyes for a brief few seconds as you slashed his throat. You wipe the knife on the bedclothes, lock the door, slip the knife back into its hiding place and stand knocking on the door at the far end of the corridor.’
    Athelstan saw the faint look of amusement in Parch-meiner’s eyes though the young man’s face remained cold and impassive.
    ‘It was then,’ Athelstan continued, ‘that you slipped the key to Sir Ralph’s chamber off your ring. You go downstairs, ask for the false key, go back up the steps and make the sudden change whilst your back is turned. You return the correct key to the guards, I have just proved two keys can look alike. You then go looking for Colebrooke.’
    ‘Oh, no!’ Philippa, her face now white and drawn, as she slumped against Sir Fulke, her eyes fixed on Geoffrey. ‘Oh, please God, no!’ she repeated.
    ‘It happened that way,’ Cranston airily declared. ‘My clerk has proved it. The guards simply saw and heard what they were supposed to.‘
    ‘Brother Athelstan!‘
    ‘Yes, Sir Fulke?’
    ‘My brother’s body was cold when the lieutenant came up.’
    ‘Of course it was,’ Cranston snapped. ‘The brazier and the fire had died, which makes me think
