You tell her, Lanie!
In one of the following sneak peeks from this Monday's Castle, our favorite medical examiner tries to talk some sense into her pal Kate Beckett. Hint: it has something to do with the feelings of a certain author and why he's acting strangely following the events of "47 Seconds."
Elsewhere: Brett Tucker guest stars on "The Limey" as a detective from Scotland Yard, someone who Castle and Beckett are introduced to in a VERY personal manner, and someone who then goes undercover with the latter on assignment.
