Echo slowly pulled out a small piece of paper and handed it to John. "The code is: DG-XXXX-XXXX-XXXX-XXXX," it read. "But there's a catch. You must use this code to recover data for a specific client. A client who has been... watching you."
Echo smiled. "You'll find out soon enough. Just use the code and trust me."
The client, whose data he had recovered, arrived at the office, overjoyed. But as John looked into their eyes, he noticed something familiar. It was the same person who had been sitting across from him in the café, watching him.
John reluctantly agreed. He entered the license code into DiskGenius, and the software sprang to life. He began the recovery process, and to his surprise, the data began to flow back.
