I said, “Jack from Glendara Taxis drove them all back to the B & B from the pub. Bob and his wife and brother.”

Molloy stared at me.

“He gave me a lift in from Malin this morning to pick up my car,” I explained.

“Good. I’ll have a chat with him.” Molloy paused. “I wondered if maybe they’d had a row, Bob and his wife.”

And with that he’d hit on exactly what I’d wanted to talk to him about. “Did you speak to Mary?”

Molloy nodded, looking at me curiously. “Yes, but only briefly. Why?”

I braced myself. “I probably shouldn’t be telling you this but, according to Mary, there was a big row between Bob Jameson and his wife, the night before last, in the B & B.”

Molloy crossed his arms. “Go on.”

“What’s the wife’s name?” I asked.

“Amanda.”

“Amanda. Well, there was a row between Bob and Amanda. Mary had to get Bob’s brother to intervene.”

Molloy narrowed his eyes. “What kind of a row?”

“Loud enough to disturb Mary and possibly the other guests. Amanda was throwing things at him apparently, things from their suitcase and washbag. According to Mary he was just taking it.”

Molloy absorbed this for a second. “So not the love’s young dream they were in the pub?”

“You saw them?”

He gave a wry smile. Public displays of affection weren’t really Molloy’s thing. “They were hard to miss.”

“Presumably they’d made up by last night.”

“Presumably,” he said. “But if they were that volatile a couple, maybe I was right about them having a row when they came back? Maybe they’re the kind of couple who fight when they drink?” Molloy straightened himself. “Okay. Thanks for letting me know. It might mean nothing, but we could do with all the help we can get, now.”

“That’s what I thought. Mary might not be too thrilled with me for telling you, but in the circumstances …”

“No, I’m glad you did.” He reached for his coat. He looked set to go. “She was being very kind to the wife when I left. Amanda wanted to go up to the church, but Mary said she’d call the priest to come down. I’ll have a longer chat with her when I get the chance, see what she knows.”

He took his coat from the hook and started to put it on, grimacing as he did so. It must have been still wet.

“And the brother, Derek?” I asked. “Did you see him?”

“He was there too, comforting Amanda. Distraught too, of course. Can’t understand what happened. Has no idea what his brother could have been doing out at Mamore Gap.” Molloy took his phone from the pocket of his coat and wiped it with his sleeve. “Unhelpfully, it’s already made the national news.”
