“Not entirely,” he said.

“What do you mean?”

“Well, you have managed to scratch ‘castle’ off your list of possible wedding venues,” he said.

“There is that,” I agreed. “Although I’m still partial to you in a kilt.”

I heard him chuckle.

We reached the bottom of the stairs. There’d been no sign of Sunny in the tunnel. No heap of blankets or traces of food on the floor. If she had come this way, then she’d only used the tunnel as a passage and hadn’t hidden in it.

“Well, this was a bust,” I said.

“Not necessarily,” Harry said. “Didn’t you find her hiding in the library after Dooney was murdered?”

I nodded. “But I assumed she went through the door while Archie and I were gone.”

“But she might have used the tunnel,” he said. “If the library has been closed off like the constable said, she could be hiding in there.”

“She did say she used the tunnel before. It’s a good place to hide,” I said. “I mean there’s plenty to read, comfy chairs, and she has her own access point.”

Harry nodded and whispered, “Let’s go.”

I followed him up the stairs, staying close to the wall. When he reached the door, the knob wouldn’t budge. It was locked from the inside.

“Blast!” Harry said. “Now we know why no one is watching the tunnel exit. The door is locked. There’s no access to the library this way.”

I maneuvered around him and looked at the lock. I glanced at Harry. “Do you have a credit card?”

“Planning to do some shopping?” he asked.

I laughed. “No. When I was in the hotel industry, they taught us the different ways people could open locked doors, hoping we’d be better at spotting security risks. One of the ways was with a credit card and a lock that looks like this sort.”

Harry lifted his eyebrows and took out his wallet. He fished out a card and handed it to me.

“Perfect.” I knelt down again and shoved the card in between the door and the frame parallel with the knob. No luck. I pushed on the door a bit and pop, the door swung open.

“I don’t know whether to be impressed or horrified,” Harry said. “I’m leaning towards impressed.”

I returned his somewhat mangled credit card. “Sorry.”

“And the pendulum swings back to horrified,” he said. He pocketed the card.

Harry put his arm in front of me, holding me in place, while he peeked around the edge of the open door to make sure it was clear. No one was waiting to clobber us with a fire poker, so that was a good sign.
