Murder most holy

the old friar snapped. ‘You were always a dreamer. Anyway, what do you want with me, a sick old man?’
    ‘Does the name Hildegarde mean anything to you?’ Brother Paul neighed with laughter.
    ‘Are you here to dig over the sins of my youth?’ he snorted, and turned his head in the direction of Athelstan’s voice. ‘My eyes are gone, Brother Athelstan, but my memory is still sharp. Hildegarde is a woman’s name. I remember you, with your dark eyes and soft heart. Do you remember what I told you above love? How dreadful it can be for a priest to meet someone he really loves?’ The old friar turned away, bony fingers scrabbling at his cheeks. ‘I once knew a woman called Hildegarde. She had the face of an angel and a heart as wicked as sin.’ He laughed. ‘But I suppose that’s not the Hildegarde you are searching for? You are looking for a German woman, an abbess, who lived — what? — a hundred and twenty, a hundred and fifty years ago.’ He paused and stared blindly at the ceiling.
    ‘What more can you tell us?’ the prior asked.
    The old man shook his head wearily. ‘I can’t, Father Superior, but the library will. Yes, yes, look in the library.’ His hand fell away. ‘Over the passing of years,’ he whispered, ‘I know the name but can’t tell you the reason why.’
    Athelstan took his hand and squeezed it gently.
    ‘Thank you, Father Paul.’
    The old friar pulled Athelstan’s wrist.
    ‘May the Lord keep you. May he show his face to you and smile. May he bless you and keep you all the days of your life.’ He gently removed his hand and they quietly left the infirmary, Athelstan guiltily realising how much he owed to and yet how much he had forgotten of his life at Blackfriars. Outside in the flower garden, Cranston went to admire a rose bush in full bloom. Athelstan took his superior’s arm and whispered urgently.
    ‘Father, we now have a number of connections; Alcuin and Callixtus were linked by the name Hildegarde. Callixtus was killed in the library, not from a fall but by a blow with a candlestick. To be blunt, I believe Callixtus was looking for some book or tract related to this Hildegarde.’ Athelstan paused. ‘Father, I believe that the name Hildegarde lies at the root of all the murders perpetrated here.’
    Father Prior took a deep breath and stared up at the blue sky. ‘I see the connections, Brother Athelstan, but what in the sweet Lord’s name does the name Hildegarde have to do with the meeting of the Inner Chapter?’ He flung up his hands in frustration. ‘You have seen our library, Brother. Shelf after shelf of books, some three to four hundred pages deep. You could spend a lifetime searching there. And how do we know the assassin hasn’t already found what Callixtus was looking for?’
    ‘Perhaps he has, but let’s be optimistic. If he hasn’t then we have checked him. Any further searching amongst the books now would attract our attention.’
    Cranston rejoined them, a young, dew-wet rose between his fingers.
    ‘I heard what you said, Father Prior, but let old Sir John apply the knife of logic. Callixtus was at the top of the ladder, yes?’ He breathed in stertorously. ‘He was therefore looking for a book on the top shelf. We know roughly where the ladder was positioned.’ Cranston stuck out his great stomach. ‘Ergo,’ he announced, mimicking Athelstan, ‘the conclusion’s obvious. Callixtus may well have discovered something about this famous Hildegarde in one of the books. Now we can’t spend our time in the library, that would alarm our quarry, but that splendid lay brother who supplies me with mead... what’s his name?’
    ‘Norbert.’
    ‘Yes, we’ll use him.’
    The prior agreed and they went back into the main monastery buildings where Anselm sent a servitor with instructions for Norbert to meet them in the library. They found the scriptorium and the library fairly deserted and those few monks working there quietly left at the prior’s request. Brother Norbert, breathless from running, soon joined them. Athelstan took the young lay brother by the arm to the spot where Brother Callixtus had lain and looked up at the shelves towering above them.
    ‘Norbert, after our business in the chapel is finished, I wish you to begin removing all the books from the three top shelves.’ He pointed to the place. ‘Only these books. I want them moved, if necessary one at a time, to the guest house without anyone seeing you. Do you
