The runaway

Nova was able to escape from the garden for the first time in 12 years, when she heard the sound of the car selling icecream. She has never run away before. Dag and I drove in different directions without finding her. At last I had call from Dag who had a call from a lady who found her and brought her home, with her pullover as a leash. The Police were on their way to pick her up, but when they got the news that I was in my way, they returned. I drove to the lady who picked her up and she told me that Nova was about to get hit by cars twice. When the icecream car returned Nova had runned in front of it.
Now I am so happy to have her back :)) but I still don't know where she managed to escape.
