Known for his best-selling mystery books, Mystic River author Dennis Lehane has penned an intriguing reward for whoever brings his beloved Beagle back home safely.

The Gone, Baby, Gone novelist, who created the renegade private investigator character Patrick Kenzie, needs a master detective of his own since his black and tan hound, Tessa, went missing from the family's Boston, Mass., home on Monday.

"Our recent and beloved rescue dog, Tessa, jumped the fence in Brookline and has been roaming through the wilds of Coolidge Corner for the last 24 hours. It's possible she's staying in some good Samaritan's home right now or has tucked herself away on a porch. But if anyone sees her or knows of her whereabouts, please reach out to this page," The Wire screenwriter wrote on his official Facebook page.

"She's smart, fast, and immeasurably sweet. She doesn't have a mean bone in her body. She's micro-chipped, but her tags were off when she was let out into the yard," he explained.

An extra motivation for anyone inspired to search for the lost Beagle was the promise from the creator of the book-turned-blockbuster movie Shutter Island that they would get a starring role in the pages of his next literary work.
