It was a crisp autumn morning in Zagreb, Croatia. The sun was shining brightly over the historic buildings and cobblestone streets of the city. Ana, a young journalist, sat at her desk, sipping her coffee and staring at a piece of paper in front of her. She was on a mission to find a person she had been searching for months – a former resident of Zagreb who had gone missing under mysterious circumstances.

Ana decided to visit the local telephone directory office, nestled in a beautiful building in the heart of the city. She pushed open the door and was greeted by a friendly receptionist.

"Our telefonski imenik po imenu i prezimenu – telephone directory by name and surname – might have what you're looking for," the receptionist said, scanning the shelves.

The only lead Ana had was a vague recollection of the person's name and surname: Ivan Marković. She had tried searching online, but to no avail. The internet was flooded with information, and it was like looking for a needle in a haystack.

After a few minutes of searching, the receptionist pulled out a large book and opened it to a page marked with a yellow sticky note.

As she walked through the streets of Zagreb, Ana couldn't help but wonder what she would find at Goriška 12. Would Ivan Marković answer the phone, or would she find another clue that would lead her closer to the truth?

The receptionist handed her a piece of paper with the information and a kind smile. "Be careful, Ana. This might be a long shot, but I hope it helps you find what you're looking for."

"Ah, here we are," the receptionist said, pointing to an entry. "Ivan Marković, address: Goriška 12, Zagreb. No phone number listed, but we might have an older entry with a contact number."
