'Anything in the paper?'

He had the day's tabloid - bought along with the coffees - open across his lap. 'Not much.'

'Anything about the case?'

'I don't think so. Relegated to oblivion.' He had a sudden thought, started patting his pockets.

'What?' For a split second, she thought maybe he'd forgotten some vital medication.

'My mobile. Must've left it on the table.'

'We've got mine.'

Yes, hooked to my ISP: what happens if someone tries calling?'

'They'll leave a message.'

'I suppose so . .. Look, about yesterday ..

'Let's pretend it never happened,' she said quickly.

'But it did.'

'I just wish it hadn't, all right?'

You're the one who was always complaining I-'

'Subject closed, Grant.' She turned to him. 'I mean it. It's either closed, or I take it to the boss - your call.'

He started to say something, but stopped himself, folded his arms across his chest. Virgin AM was playing quietly on the stereo. She liked it; helped her wake up. Grant wanted something newsy, Radio Scotland or Radio Four.

'My car, my stereo,' was all she'd said to that.

Now he asked her to repeat what she'd already told him about 212 the Farmer's call. She did, glad that they were staying off the subject of the clinch.

Grant sipped his coffee while she spoke. He was wearing sunglasses, though there was no sun. They were Ray-Bans, tortoiseshell frames.

'Sounds good,' he said when she'd finished.

'I think so,' she agreed.

'Almost too easy.'

She snorted. 'So easy we almost missed it.'

He shrugged. 'It didn't take any skill, that's what I'm saying. It's the sort of thing you either know or you don't.'

'Like you said, a different kind of clue.'

'How many Masons do you suppose Philippa Balfour knows?'

'What?'

'It's how you found out. How would she have worked it out?'

'She was studying art history, wasn't she?'

'True. So she might have come across Rosslyn Chapel in her studies?'

'Possibly.'

'And would Quizmaster have known that?'

'How could he?'

'Maybe she told him what she was studying.'

'Maybe.'

'Otherwise, it's just not the sort of clue she'd have been able to get. Do you see what I'm saying?'

'I think so. You're saying it needed specialist knowledge that the previous clues didn't?'

'Something like that. Of course, there is one other possibility.'

'Which is?'

'That Quizmaster knew damned fine she'd know a little of Rosslyn Chapel, whether she told him what she was studying or not.'

Siobhan saw what he was getting at. 'Someone who knows her? You're saying Quizmaster is one of her friends?'

Grant peered at her over the top of his Ray-Bans. 'Wouldn't surprise me if Ranald Marr turned out to be a Mason, man in his line of work 'No, nor me,' Siobhan said thoughtfully. 'We might just have to go back and ask him.'

They turned off the main road and drove into the village of Roslin. Siobhan parked the car beside the chapel's gift shop. The door was locked tight.

213 'Place doesn't open till ten,' Grant said, reading from the notice. 'How long do you reckon we've got?'

'If we wait till ten, not very long.' Siobhan was sitting in the car, checking that there were no new e-mails for her.

'There must be somebody.' Grant banged on the door with his fist. Siobhan got out of the car and studied the wall surrounding the chapel grounds.

'Any good at climbing?' she asked Grant.

'We could give it a go,' he said. 'But what if the chapel's locked too?'

'What if someone's in there giving it a quick spit and polish?'

He nodded. But then there was the sound of a bolt being drawn back. The door opened and a man stood there.

'We're not open yet,' he said sternly.

Siobhan showed him her warrant card. 'Police officers, sir. Afraid we can't wait.'

They followed him along a path towards the chapel's side door. The building itself was covered with a huge canopy. From her previous visit, Siobhan knew there was a problem with the roof. It had to dry out before work could be done on it. The chapel was small on the outside, but seemed larger inside, a trick of its ornate decoration. The ceiling itself was stunning, even if much of it was green with damp and decay. Grant stood in the central aisle, gawping much as she had done the first time she'd come here.

'It's incredible,' he said quietly, his words echoing back off the walls. There were carvings everywhere. But Siobhan knew what she was looking for, and walked straight towards the Apprentice Pillar. It was next to some steps leading down to the sacristy. The pillar was about eight feet high, carved ribbons snaking down it.

'This it?' Grant said.

'This is it.'

'So what are we looking for?'

'We'll know when we find it.' Siobhan ran her hands over the cool sufface of the pillar, then crouched down. Intertwined dragons were coiled around the base. The tail of one of them, twisting back on itself, had left a small nook. She reached in with finger and thumb and brought out a small square of paper.

'Bloody hell,' Grant said.

She didn't bother with gloves or an evidence bag, knew by now that Quizmaster wouldn't have left anything useful to Forensics. It was a piece of notepaper, folded over three times. She unfolded it, Grant shifting so they could both see what was printed there.

214 You are the Seeker. Your next destination is Helibank. Instructions to follow.

'I don't get it,' Grant said. 'All of this, just for that?' His voice was rising Siobhan read the message through again, turned the paper over. Its other side was blank. Grant had spun on his heels and kicked air.

'Bastard!' he called out, earning a frown from the guide. 'I bet he's having a bloody good laugh, seeing us chasing all over the place!'

'I think that's part of it, yes,' Siobhan agreed quietly. He turned to her. 'Part of what?'

'Part of the attraction for him. He likes to see us being run ragged.'

Yes, but he doesn't see us, does he?'

'I don't know. I sometimes get the feeling he might be watching.' Grant stared at her, then walked up to the guide. 'What's your name9'

'William Eadie.'

Grant had his notebook out. 'And what's your address, Mr Eadie?' He started to take down Eadie's details.

'He's not the Quizmaster,' Siobhan stated.

'The who?' Eadie asked, his voice wavering.

'Never mind,' Siobhan said, dragging Grant away by the arm. They went back to the car, and Siobhan started typing an e-mail: Ready for Hellbank clue.

She sent it, then sat back.

'Now what?' Grant asked. Siobhan shrugged. But then the laptop announced there was a new message. She clicked to read it.

Ready to give up? That's a surer thing.

Grant let out a hiss of breath. 'Is this a clue or a taunt?'

'Maybe both.' Another message came through: Hellbank by six tonight.

Siobhan nodded. 'Both,' she repeated.

'Six? He's only giving us eight hours.'

'No time to waste then. What's a surer thing?'

'Not a clue.'

She looked at him. You don't think it's a clue?'

He forced a smile. 'That's not what I meant. Let's take another look at it.' Siobhan put the message back up on the screen. You know what it looks like?'

'What?'

215 'A crossword clue. I mean, it's not quite grammatical, is it? It almost makes sense, but doesn't.'

Siobhan nodded. 'Like it's a bit strained?'

'If it was a crossword clue . . .' Grant pursed his lips. A little vertical crease appeared between his eyebrows as he concentrated. 'If it was a clue, then "give up" could mean "yield", as in yielding meaning. Do you see?'

He fumbled in his pocket, brought out his notebook and pen. 'I need to see it written down,' he explained, copying out the clue. 'It's a classic crossword construction: part of it tells you what you have to do, part is the meaning you'll have if you do it.'

'Keep going. You might start making sense soon.

He smiled again, but kept his eyes on the words in front of him. 'Let's say it's an anagram. "Ready to give up ... that's a surer". If you give up - meaning render or use - the letters in "that's a surer", you'll get a word or words meaning a "thing".'

'What sort of thing?' Siobhan could feel a headache coming on.

'That's what we have to find out.'

'If it's an anagram.'

'If it's an anagram,' Grant conceded.

'And what's any of it got to do with Hellbank, whatever Hellbank is?'

'I don't know.'

'If it is an anagram, isn't that too easy?'

'Only if you know how cros swords work. Otherwise you'd read it literally, and it wouldn't mean anything at all.'

'Well, you've just explained it and it still sounds like gobbledy- gook to me.'

'Then aren't you lucky I'm here? Come on.' He tore off a fresh sheet of paper and handed it to her. 'See if you can unscramble "that's a surer 'To make a word that means a thing?'
