Detective Peter Pux sat at his desk, surrounded by piles of documents and files. He had been working on the case of the missing Mona Lisa for hours, and he was no closer to finding any leads.

Just as he was about to take a break, his phone rang. It was Detective Sarah Smith.

"Peter, I've got some information for you," Sarah said. "I was just at the museum, and I spoke with the security guard on duty the night the painting was stolen. He remembers seeing a group of people acting suspiciously around the Mona Lisa just before the alarm went off."

Peter's ears perked up. This was the first real lead they had on the case.

"Do we have any descriptions of these suspects?" he asked.

"Not much," Sarah replied. "The security guard only caught a glimpse of them before they ran off. But he did say that one of them was a woman with long blonde hair and another was a man with a distinctive tattoo on his neck."

Peter jotted down the descriptions in his notebook. This was a start, at least.

"I'll start running some checks on anyone matching these descriptions," he said. "Maybe we'll get lucky and one of them will turn up something."

"I hope so," Sarah said. "We need to find that painting before it's gone for good."

With that, Peter hung up the phone and set to work, determined to track down the suspects and bring the thief to justice.
