Ava and Rachel walked in silence, their eyes scanning the surroundings. They ducked into a small alleyway, out of sight from potential watchers.
"Okay, let's get down to business," Rachel said, pulling out her phone. "We need to dig deeper into the evidence."
Ava nodded, her mind racing with questions. "Where do we start?"
Rachel began scrolling through her notes. "We have a few leads. Let's start with the company mentioned in the documents."
Ava's eyes widened as she scanned the notes. "This is huge. If true, it could bring down some very powerful people."
Rachel's expression was grim. "I know. That's why we have to be careful."
As they pored over the evidence, Ava's phone buzzed with an unknown number. She hesitated before answering.
"Hello?"
"Ava, you're playing with fire," a low, menacing voice said. "Drop the investigation."
Ava's heart racing, she hung up. "We have a problem."
Rachel's eyes locked onto Ava's. "What is it?"
Ava's voice was steady. "They know we're investigating."
