The Dog with a key

You've no sooner shut the door than your phone chimes with a text message.

"Black Explorer in underground. Key under the mat." The number is blocked, but you have no doubt this is from Tony Dogs, telling you about the vehicle Vincent Maglio referred to. Putting the box of cupcakes in the fridge, you leave your cottage and head to the parking garage, wanting to see what they've given you.

It isn't hard to find. It's the only black SUV in the lot, and looks to be in good shape despite being a few years old. You open the door and look under the mat, finding a set of keys just as promised.
