Christy was packing up the useful materials in the room when she received a call from Ferne, "Your brother is missing."
After hanging up the phone, Christy directly turned on her computer and began to locate Noah.
Ferne guessed correctly. Noah was on his way to the hospital. He needed to make sure that the tracker was not found by others. If the doctors or the policemen found it, then they would know that there was a mole at the last group event.
Christy packed everything in a paper box and sealed it with tapes. She put the box into the storage cabinet in the hall downstairs and locked the cabinet. Then, she put on her hat and mask and went to the garage.
Because Ferne's car was too expensive and eye-catching, Noah bought two cheaper grey cars, one for him and one for Christy.
At this moment, there was one car in the garage. Christy went into the car and started the engine. She called Noah but no one picked up the phone.
