A Weekend at the Grand Hotel — Mary Labatt

Join Sam: Dog Detective on her fifth funny adventure as she enjoys a little family holiday at the Grand Hotel. And what could be more exciting than the bustling lobby of a big hotel? Guests arrive, people meet -- and signals are exchanged. For Sam, this can mean only one thing: spies, and lots of them! Everyone seems awfully suspicious, what with envelopes being passed back and forth, people creeping out of guests' rooms and secretly using the back stairs. Something's definitely up, and Sam is sure to figure it out -- if only Jennie and Beth will help her.
