The Son of Neptune

closer, she recoiled and started to shriek. Then Hazel tried, and Ella let her pour some nectar on her back. The wound began to close.

Hazel smiled. ‘See? That’s better.’

‘Phineas is bad,’ Ella insisted. ‘And weed whackers. And cheese.’

‘Absolutely,’ Percy agreed. ‘We won’t let him hurt you again. We need to figure out how to trick him, though. You harpies must know him better than anybody. Is there any way we can trick him?’

‘N-no,’ Ella said. ‘Tricks are for kids. 50 Tricks to Teach Your Dog, by Sophie Collins, call number six-three-six -’

‘Okay, Ella.’ Hazel spoke in a soothing voice, like she was trying to calm a horse. ‘But does Phineas have any weaknesses?’

‘Blind. He’s blind.’

Frank rolled his eyes, but Hazel continued patiently, ‘Right. Besides that?’

‘Chance,’ she said. ‘Games of chance. Two to one. Bad odds. Call or fold.’

Percy’s spirits rose. ‘You mean he’s a gambler?’

‘Phineas s-sees big things. Prophecies. Fates. God stuff. Not small stuff. Random. Exciting. And he is blind.’

Frank rubbed his chin. ‘Any idea what she means?’

Percy watched the harpy pick at her burlap dress. He felt incredibly sorry for her, but he was also starting to realize just how smart she was.

‘I think I get it,’ he said. ‘Phineas sees the future. He knows tons of important events. But he can’t see small things – like random occurrences, spontaneous games of chance. That makes gambling exciting for him. If we can tempt him into making a bet …’

Hazel nodded slowly. ‘You mean if he loses, he has to tell us where Thanatos is. But what do we have to wager? What kind of game do we play?’

‘Something simple, with high stakes,’ Percy said. ‘Like two choices. One you live, one you die. And the prize has to be something Phineas wants … I mean, besides Ella. That’s off the table.’

‘Sight,’ Ella muttered. ‘Sight is good for blind men. Healing … nope, nope. Gaia won’t do that for Phineas. Gaia keeps Phineas b-blind, dependent on Gaia. Yep.’

Frank and Percy exchanged a meaningful look. ‘Gorgon’s blood,’ they said simultaneously.

‘What?’ Hazel asked.

Frank brought out the two ceramic vials he’d retrieved from the Little Tiber. ‘Ella’s a genius,’ he said. ‘Unless we die.’

‘Don’t worry about that,’ Percy said. ‘I’ve got a plan.’

XXVIII Percy

THE OLD MAN WAS RIGHT WHERE they’d left him, in the middle of the food truck parking lot. He sat on his picnic bench with his bunny slippers propped up, eating a plate of greasy shish kebab. His weed whacker was at his side. His bathrobe was smeared with barbecue sauce.

‘Welcome back!’ he called cheerfully. ‘I hear the flutter of nervous little wings. You’ve brought me my harpy?’

‘She’s here,’ Percy said. ‘But she’s not yours.’

Phineas sucked the grease off his fingers. His milky eyes seemed fixed on a point just above Percy’s head. ‘I see … Well, actually, I’m blind, so I don’t see. Have you come to kill me, then? If so, good luck completing your quest.’

‘I’ve come to gamble.’

The old man’s mouth twitched. He put down his shish kebab and leaned towards Percy. ‘A gamble … how interesting. Information in exchange for the harpy? Winner take all?’

‘No,’ Percy said. ‘The harpy isn’t part of the deal.’

Phineas laughed. ‘Really? Perhaps you don’t understand her value.’

‘She’s a person,’ Percy said. ‘She isn’t for sale.’

‘Oh, please! You’re from the Roman camp, aren’t you? Rome was built on slavery. Don’t get all high and mighty with me. Besides, she isn’t even human. She’s a monster. A wind spirit. A minion of Jupiter.’

Ella squawked. Just getting her into the parking lot had been a major challenge, but now she started backing away, muttering, ‘“Jupiter. Hydrogen and helium. Sixty-three satellites.” No minions. Nope.’

Hazel put her arm around Ella’s wings. She seemed to be the only one who could touch the harpy without causing lots of screaming and twitching.

Frank stayed at Percy’s side. He held his spear ready, as if the old man might charge them.

Percy brought out the ceramic vials. ‘I have a different wager. We’ve got two flasks of gorgon’s blood. One kills. One heals. They look exactly the same. Even we don’t know which is which. If you choose the right one, it could cure your blindness.’

Phineas held out his hands eagerly. ‘Let me feel them. Let me smell them.’

‘Not so fast,’ Percy said. ‘First you agree to the terms.’

‘Terms …’ Phineas was breathing shallowly. Percy could tell he was hungry to take the offer. ‘Prophecy and sight … I’d be unstoppable. I could own this city. I’d build my palace here, surrounded by food trucks. I could capture that harpy myself!’

‘N-noo,’ Ella said nervously. ‘Nope, nope, nope.’

A villainous laugh is hard to pull off when you’re wearing pink bunny slippers, but Phineas gave it his best shot. ‘Very well, demigod. What are your terms?’

‘You get to choose a vial,’ Percy said. ‘No uncorking, no sniffing before you decide.’

‘That’s not fair! I’m blind.’

‘And I don’t have your sense of smell,’ Percy countered. ‘You can hold the vials. And I’ll swear on the River Styx that they look identical. They’re exactly what I told you: gorgon’s blood, one vial from the left side of the monster, one from the right. And I swear that none of us knows which is which.’

Percy looked back at Hazel. ‘Uh, you’re our Underworld expert. With all this weird stuff going on with Death, is an oath on the River Styx still binding?’

‘Yes,’ she said, without hesitation. ‘To break such a vow … Well, just don’t do it. There are worse things than death.’

Phineas stroked his beard. ‘So I choose which vial to drink. You have to drink the other one. We swear to drink at the same time.’

‘Right,’ Percy said.

‘The loser dies, obviously,’ Phineas said. ‘That kind of poison would probably keep even me from coming back to life … for a long time, at least. My essence would be scattered and degraded. So I’m risking quite a lot.’

‘But if you win, you get everything,’ Percy said. ‘If I die, my friends will swear to leave you in peace and not take revenge. You’d have your sight back, which even Gaia won’t give you.’

The old man’s expression soured. Percy could tell he’d struck a nerve. Phineas wanted to see. As much as Gaia had given him, he resented being kept in the dark.

‘If I lose,’ the old man said, ‘I’ll be dead, unable to give you information. How does that help you?’

Percy was glad he’d talked this through with his friends ahead of time. Frank had suggested the answer.

‘You write down the location of Alcyoneus’s lair ahead of time,’ Percy said. ‘Keep it to yourself, but swear on the River Styx it’s specific and accurate. You also have to swear that if you lose and die, the harpies will be released from their curse.’

‘Those are high stakes,’ Phineas grumbled. ‘You face death, Percy Jackson. Wouldn’t it be simpler just to hand
