Books in the Tim Brown Mysteries series

In his fifth month of 'delving' during his year-long sabbatical in 1999, newspaper publisher Tim Brown realizes something odd is going on that may impact him and his business. And it may relate to the much bigger, and possibly darker, 'Project Sweetland' that he and his team at the newspaper are looking into. Can he move forward in directions he had not anticipated, despite pugnacious opposition?

What's the difference between a delver and a private detective? Tim Brown is about to try to find out, as a challenge lands on his desk. It's the reverse of a locked-room puzzle, since not just a room but a whole building seems to have disappeared.
