Arianna spent time washing up in the bathroom after getting rid of her ruined sneakers and walking back to the main house barefooted. If there was one thing mobsters enjoyed, it was having a spacious residence and Draven's family property stretched for miles with acres of empty land.
It was a private property with lots of hidden traps and no one dared to trespass without the fear of losing a limb. The Draven reputation precedes them so even the daredevils looking for a thrill don't cross the property.
Not to mention the number of soldiers that kept the place safe. Arianna suspected they did this on purpose in case of a police raid, it would take enough resources to cover much ground - by then, vital evidence would be destroyed.
