The House of Hades (Heroes of Olympus Book 4)

driver’s box were giant feathery wings. Wrapped around the rim of the left wheel, a spotted python snored loudly.
    Frank hadn’t known that pythons could snore. He hoped he hadn’t done that himself in python form last night.
    ‘Set your friend here,’ said the man in denim.
    Frank placed Hazel gently on the bed. He removed hersword and tried to make her comfortable, but she was as limp as a scarecrow. Her complexion definitely had a greenish tint.
    ‘What were those cow things?’ Frank demanded. ‘What did they do to her?’
    ‘
Katoblepones
,’
said their host. ‘Singular:
katobleps
. In English, it means
down-looker
. Called that because –’
    ‘They’re always looking down.’ Nico smacked his forehead. ‘Right. I remember reading about them.’
    Frank glared at him. ‘
Now
you remember?’
    Nico hung his head almost as low as a
katobleps
. ‘I, uh … used to play this stupid card game when I was younger. Mythomagic. The
katobleps
was one of the monster cards.’
    Frank blinked. ‘I played Mythomagic. I never saw that card.’
    ‘It was in the
Africanus Extreme
expansion deck.’
    ‘Oh.’
    Their host cleared his throat. ‘Are you two done, ah,
geeking out
, as they say?’
    ‘Right, sorry,’ Nico muttered. ‘Anyway,
katoblepones
have poison breath and a poison gaze. I thought they only lived in Africa.’
    The man in denim shrugged. ‘That’s their native land. They were accidentally imported to Venice hundreds of years ago. You’ve heard of Saint Mark?’
    Frank wanted to scream with frustration. He didn’t see how any of this was relevant, but, if their host could heal Hazel, Frank decided maybe it would be best not to make him angry. ‘Saints? They’re not part of Greek mythology.’
    The man in denim chuckled. ‘No, but Saint Mark is thepatron saint of this city. He died in Egypt, oh, a long time ago. When the Venetians became powerful … well, the relics of saints were a big tourist attraction back in the Middle Ages. The Venetians decided to steal Saint Mark’s remains and bring them to their big church of San Marco. They smuggled out his body in a barrel of pickled pig parts.’
    ‘That’s … disgusting,’ Frank said.
    ‘Yes,’ the man agreed with a smile. ‘The point is you can’t do something like that and not have consequences. The Venetians unintentionally smuggled something
else
out of Egypt – the
katoblepones
. They came here aboard that ship and have been breeding like rats ever since. They love the magical poison roots that grow here – swampy, foul-smelling plants that creep up from the canals. It makes their breath even more poisonous! Usually the monsters ignore mortals, but demigods … especially demigods who get in their way –’
    ‘Got it,’ Frank snapped. ‘Can you cure her?’
    The man shrugged. ‘Possibly.’
    ‘
Possibly?
’
Frank had to use all his willpower not to throttle the guy.
    He put his hand under Hazel’s nose. He couldn’t feel her breath. ‘Nico, please tell me she’s doing that death-trance thing, like you did in the bronze jar.’
    Nico grimaced. ‘I don’t know if Hazel can do that. Her dad is technically Pluto, not Hades, so –’
    ‘Hades!’ cried their host. He backed away, staring at Nico with distaste. ‘So
that’s
what I smell. Children of the Underworld? If I’d known
that
, I would never have let you in!’
    Frank rose. ‘Hazel’s a good person. You promised you would
help
her!’
    ‘I did
not
promise.’
    Nico drew his sword. ‘She’s my sister,’ he growled. ‘I don’t know who you are, but if you can cure her you have to, or so help me by the River Styx –’
    ‘Oh, blah, blah, blah!’ The man waved his hand. Suddenly where Nico di Angelo had been standing was a potted plant about five feet tall, with drooping green leaves, tufts of silk and half a dozen ripe yellow ears of corn.
    ‘There,’ the man huffed, wagging his finger at the corn plant. ‘Children of Hades can’t order me around! You should talk less and listen more. Now at least you have
ears
.’
    Frank stumbled against the bed. ‘What did you – why –?’
    The man raised an eyebrow. Frank made a squeaky noise that wasn’t very courageous. He’d been so focused on Hazel, he’d forgotten what Leo had told them about the guy they were looking for. ‘You’re a god,’ he remembered.
    ‘ Triptolemus .’ The man bowed. ‘My friends call me Trip, so don’t call me that. And if you’re another child of
