The beloved rescue dog of acclaimed novelist Dennis Lehane (of Mystic River, Shutter Island, and Gone, Baby, Gone fame) recently went missing in Brookline — the suburban Boston town Lehane calls home.

Tessa, a black-and-tan beagle, jumped the fence on Monday and has been missing for the past 48 hours. Though the dog is "micro-chipped," per Lehane, "her tags were off when she was let out into the yard."

According to a local ABC affiliate, She was last spotted near a Hess gas station in the Boston neighborhood of Allston, though Lehane believes she has since returned to Brookline and is "roaming through the wilds of Coolidge Corner" — the town's main commercial intersection.

Lehane has offered a one-of-a-kind reward to anyone who helps Tessa get home safely: Their very own character in his next book. "No, really!" he insists.

So, if you've been saving your keen beagle-finding skills for just the right character-naming reward from a best-selling author, this is probably as good as it gets.
