The bad news: Novelist/screenwriter Dennis Lehane’s beloved dog has gone missing.

The good news: If you find her, the author of Mystic River and Shutter Island will name a character after you in his next book. There’s no guarantee that character will be sane and/or safe from a grisly death, though.

Lehane posted his unusual offer on Facebook Tuesday, explaining that the pooch — a black-and-tan beagle who answers to the name ‘Tessa’ — had jumped the fence at his Brookline, Mass. home 24 hours previously. “She’s smart, fast, and immeasurably sweet,” the Edgar Award winner wrote. “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.

“Naming of character in the next book for anyone who gets her back to us!” Lehane continued, adding, “No, really!” He also posted a photo of the (adorable) dog in question for good measure.

So far, nobody seems to have located Tessa — though over 100 people have commented on Lehane’s post to wish the writer well.

In a strange coincidence, the author’s next project is a film called Animal Rescue that focuses, in part, on a missing pit bull. Lehane wrote the script, as well as the short story on which it’s based. The movie stars Tom Hardy and Noomi Rapace and will begin pre-production in early 2013.
