The Gallows Murders

repeated. ‘Yes, my lord.'
    Quicksilver pulled a face and clicked his fingers. 'An undoubted case of Rotterus Arsicus,' he declared grandly. ‘Is it contagious?' the steward asked.
    'Don't be stupid!' Quicksilver replied. 'But it's a savage ailment. I have treated it before in Montpellier and Salerno.' 'Is it fatal?' the landlord asked hopefully.
    'How long have the victims been suffering?' Quicksilver demanded gravely. 'About three days. Yes, my lord, this is the third day.'
    'It takes a week,' Quicksilver declared pompously, ‘before the real rottenness sets in and death ensues.'
    The steward nearly dropped his tankard, and had to be helped to a stool. I don't think he was really bothered about the Poppletons, but the prospect of losing his sinecure made him weak at the knees.
    'Oh, good sir,' he gasped, mopping his brow, 'can you help?' 'Of course!'
    'And how much will it cost?' The steward screwed his face up into what he thought was a shrewd look.
    'Cost! Cost! You dare to talk to me about cost? Me, Dr Mirabilis!'
    Quicksilver half rose out of his chair, but the steward threw himself on his knees. 'My lord, come with me, please!' he begged.
    The good physician finally agreed and, without even a glance at me, stepped out of the tavern, the steward trotting ahead of him. I waited till they had gone, then fled the place to laugh myself witless in a ditch. Well, the bait was down, the lure was out. Later that night I stole back and met Quicksilver under the moonlight by the gibbet near the crossroads. The rogue was laughing fit to burst.
    There's no wine left in that cask,' he declared. ‘Even when they were sick they insisted on drinking it. To fortify,' he gravely mimicked the Great Mouth's tone, 'our poor bodies.' 'And you recommended?'
    Quicksilver shrugged. 'I followed your instructions. I gave them no medicine, but told them not to eat or drink anything except sugared water, and that I would return tomorrow evening.' 'And?' I asked hopefully.
    Then I’ll strike. I’ll continue the medication but develop the seeds I sowed today. How Rotterus Arsicus is really a mysterious disease, more the product of the humours of the mind than anything else. They must have done great ill, maligned someone: this has infected the soul, turned the humours morbid, which expresses itself in horrid pustules and looseness of the bowels.' Quicksilver smiled and arranged his cloak, easing the cramp from his limbs as he sat on a stile.
    The gulls will bite,' he said softly. ‘I’ll be well paid. You'll have your revenge and its heigh ho back to London.' He pointed to the skeleton which swung in its iron gibbet from the scaffold. ‘Do you think we'll end up like that, Roger? A pile of musty bones? The plaything of some evening breeze at a lonely crossroads?'
    I stared at the scaffold, bathed in the light of a summer moon, and a shiver ran down my spine. It wasn't usual for Quicksilver to be so melancholic. I jumped down from the fence and clapped my companion on the shoulder.
    'He wasn't a rogue,' I declared. 'Don't you know your anatomy, Dr Mirabilis? That poor fellow suffered from Rotterus Arsicus and, in a fit of rage, went out and killed someone.'
    Quicksilver burst out laughing. I shook his hand and told him that, if all went well, ‘I’d deliver the rest of the coins, and set off back to the manor.
    In the end, all did go well. Every night I went back to the White Hart, where Quicksilver loudly reported how the Poppletons were progressing. The steward sat beside him, nodding solemnly, opening his mouth in one glorious hymn of praise for old Quicksilver's skills. So the trap was closed. On Saturday night I could tell from the charlatan's face that all was going as planned: he designed to notice me in the inglenook corner, brought me a cup of claret and raised his own in a toast, his eyes full of devilment.
    The next morning, my master and I went down to church for morning Mass. Benjamin was still subdued. Indeed, I had hardly seen him or talked to him. I could tell the insults had rankled deep.
    Accordingly, you can imagine my glow of triumph when Vicar Doggerell stood on the altar steps, hands extended, his fat, foolish face wreathed in smiles. He beamed at the Poppletons, now returned to rude health, sitting in one pew, and then at my master.
    This week,' the old fool declared, 'the parish has seen a great victory. One of our noblest families snatched from the jaws of death.'
    He turned and, clasping his hands, bowed
