Anonymous Tipoff

Fabian was dealing with some paperwork when he noticed his phone vibrating. He took it from the table and saw that Arlan was calling him. 'It's him!' 

"Hello, Arlan! Do you need anything from me?" 

"Good morning, Uncle Fabian! It's like this... I have something important to discuss with you and it's best if we speak face to face. Do you have some time tonight?" Arlan wanted to be careful so he had to meet Fabian in person. With today's technology, someone could tap one's phone without the owner's knowledge. If that happens, every activity including phone calls done by the owner of the phone would be transmitted to a third party. Arlan was confident that his phone was safe, but things might not be the same for Fabian's device. 

Fabian was slightly taken aback by his words. "Is it serious?" He asked in a low voice.

"Yes." Arlan answered calmly.
