Houston waited for near an hour, but when it became completely dark outside and Apryl didn't come back out, he knew that he couldn't wait around any longer. Brian hadn't done anything suspicious aside from slamming that could be heard throughout the house. There was nothing to indicate that they needed to be involved.
The longer he waited, the more the detective knew that it would do no good for him to stay there any longer. He would have to come back later to try and speak with the female werewolf. He doubted her family would appreciate a stranger walking in there right now with the tension going on.
