As you can tell by my five-star rating, I truly loved tonight’s episode of Castle. “Get a Clue” was such a delight to watch because once again, it recalled the playful and mischievous episodes of earlier seasons, and sparked a longstanding curiosity of mine —historical treasure. I mean, who doesn’t believe in secret passageways, coded messages, hidden clues, and ultimately, buried treasure secreted by our founding fathers?! I’m pretty sure Richard Castle (Nathan Fillion) and I would be the best of friends!
