Rick Castle went back to school on Castle Season 8 Episode 3. Alas, he did not win Kate Beckett back as his wife.
Fear not, however: the author-turned-investigator will be back at it on Castle Season 8 Episode 4.
Titled "What Lies Beneath," the installment will find Castle dealing with the death of his idol, a reclusive author who is killed... somehow.
Look for Castle to look into his hero's murder, while he and Beckett "discover that truth is stranger than fiction," according to the official network synopsis.
