A moment later, the cart was swallowed by shadows as it entered the mouth of the longest arbour Payne had ever seen. Hundreds of arching metal poles had been planted into the ground, approximately one foot apart on both sides of the steep path. The poles were connected by several horizontal rails, which formed a series of one-foot squares that functioned as a trellis. Over the years, dozens of trees had been trained to grow over the extensive framework. The resulting tunnel – a combination of vines, leaves and branches – shielded them from the sun and blocked their view of water steps on their left that flowed towards the ornate castle behind them.
Ulster admired the vegetation. ‘Is this the gartenlaube you mentioned?’
She nodded. ‘We entered it from the east. It arches all the way up to a music pavilion on top of the hill before it arches back down to the western side of the grounds. When viewed from the palace windows, the arbour looks like a green rainbow on the hillside.’
Payne leaned forward. ‘And what does the arbour have to do with swans?’
‘Nothing,’ she admitted as they reached a fork in the path.
‘Then I’m confused. I thought gartenlaube helped you solve the riddle?’
The arbour continued to arch gently around to the left while an uncovered trail veered off to the right. This new trail went straight up the hill towards the north. She made the turn before she answered his question. ‘It did help me solve the riddle. Back in Ludwig’s time, gartenlaube had multiple meanings. Sometimes it meant garden arbour, which is the literal translation of the term. But in the world of landscaping, it was a generic term for man-made garden. If you think about it, that’s what an arbour is: the trees and trellis were shaped by man.’
‘What’s your point?’ Payne asked.
‘My point is simple,’ she said as she drove up the steep path, ‘there’s more than one man-made garden on the Linderhof grounds. The one we’re going to was Ludwig’s personal favourite. It’s called the Venus Grotto.’
‘Does it have swans?’ Jones wondered.
She smiled as she parked their cart next to a large rock formation that was covered in green moss. ‘The Venus Grotto has everything. I’m sure you’ll be impressed.’
Payne climbed out of his seat and stared at the spacious grounds. The approach of autumn had splashed the trees with a vibrant mix of colours. Everywhere he looked, he saw reds and yellows, oranges and gold, all mixed against a palette of greens. If the Venus Grotto was half as impressive as the leaves around him, he would be pleasantly surprised.
‘Is it much of a hike?’ Payne asked.
She shook her head. ‘Not at all.’
‘Then what are we waiting for?’
‘I wanted to see if you would spot it.’
‘Spot what?’
‘The secret entrance to the grotto.’
He looked at her. ‘The what?’
‘You heard me. The secret entrance to the grotto.’
In unison, Payne, Jones and Ulster turned towards the large mound behind them. Standing twelve feet in height, the rugged formation appeared to be a natural extension of the hillside. Weeds grew from the cracks in the grey rocks. Small trees sprang from the crevices. If they had walked past it, they wouldn’t have given it a second thought. Everything about it looked as though it belonged, as if it had been there since the dawn of time. Naturally curious, Jones tapped one of the moss-covered stones to make sure it was real. Then he tapped another. Payne and Ulster quickly followed suit, each of them hoping to find the entrance first.
Payne called over his shoulder. ‘If you’re messing with us, I’m going to be pissed.’
She laughed at his comment. ‘I swear, I’m not messing with you. There really is a secret entrance to the grotto. In fact, Ludwig designed several secret doors and passageways in his castles – not to mention a number of slick contraptions that catered to his dream world. Believe it or not, some of them were quite brilliant.’
Payne glanced at her. ‘Such as?’
‘When Ludwig was entertaining guests, he didn’t want to be disturbed by servants. He felt they invaded his privacy and ruined the fantasies he was trying to create. Obviously this was a major problem when he was throwing a dinner party for a lot of people. No servants meant no food. So Ludwig designed a special dining room in the Linderhof that met his personal needs. The room featured a full-length table that could be lowered into the kitchen below so his servants could stock the table and raise it back up without being seen.’
Payne smiled. ‘You’ve got to be kidding me.’
‘Trust me, that’s nothing compared to what you’ll see inside the grotto. That is, if you guys can find the way in. I thought one of you was supposed to be a detective?’
Jones, who was a licensed investigator, took the comment as a personal challenge. Less than thirty seconds later, he found a tiny metal handle imbedded in the rock face. Without waiting for Heidi’s permission, Jones yanked on the latch. A soft click could be heard in the centre of the mound, followed by a loud rumble. Suddenly the large boulder in the middle of the formation started to twist to the left. Unsure of what was happening, Jones jumped back and watched as the boulder turned on a centre axis. The left side of the rock went in while the right side swivelled out. Once the rock stopped moving, Jones stared at the resulting fissure. It was seven feet tall and three feet wide. Beyond it, a narrow corridor stretched deep into the darkness.
Jones glanced back at the group. ‘I’m not sure, but I think I found it.’

Armed with flashlights, the foursome walked single file into the man-made cave at the northern end of the Linderhof grounds. Heidi led the way, followed by Jones, Ulster and Payne. To ensure their privacy, he closed the door behind them. When the grounds were officially open, the narrow corridor would be awash with floor lights for the safety of the crowds. But that was later. For the moment, nothing was turned on.
‘Watch your heads,’ she called out from the front.
Fake stalactites dangled from the ceiling above as stalagmites rose from the floor, as if the group was passing through a sharp set of teeth. Payne wasn’t sure where they were going or what they were about to see, but he sensed something great was lurking ahead. Outside, he’d had his doubts about this place until that giant boulder had twisted aside like something from a movie. That had changed everything. Suddenly, he felt like a little kid again exploring one of the walk-through rides at Kennywood, an amusement park near Pittsburgh. All that was missing was the taste of cotton candy and the safety of his grandfather’s hand.
‘How old is this place?’ Jones asked in the darkness.
Heidi answered as she opened the grotto’s control panel, which was hidden behind a fake boulder. ‘It was finished in 1877. Workers installed a framework of steel girders and pillars. They covered them with cement, sometimes laid over canvas, then sculpted them into shape.’
Payne shone his flashlight to the far left. At first glance, it looked like the ground was rippling. He assumed it was an optical illusion caused by his light until he heard the dripping of water. ‘What’s out there? Is that a fountain?’
Heidi put her hand on the switch. ‘Nope. Something better.’
‘Like what?’ he wondered.
Instead of answering, she started flipping switches. One by one, lights popped on throughout the grotto. Suddenly, the stalactites and stalagmites were bathed in blue light. Then the ceiling above them turned gold. An instant later, their pathway lit up like a ramp in a movie theatre, followed by a series of recessed lights in a painted alcove. Finally, the ground to the left started to glow – blue at first and then an alien green. It took a few seconds for Payne’s eyes to adjust, but when they did, he was stunned by the sight. The entire time he had been walking in the darkness, he had been strolling beside an underground lake.
