Always dreamed of being in a Dennis Lehane novel? Well, here's your chance.


The award-winning author of "Gone Baby Gone," "Mystic River" and many other books, is offering to name a character in his next book after the person who is able to find and return his missing dog.


"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," Lehane posted on his Facebook page Tuesday evening.


The Dorchester native said the Beagle is microchipped, but that her tags were not on her when she was let out in the yard. He described her as "smart, fast, and immeasurably sweet" and without a mean bone in her body.


He then offered a reward that would only be appealing when it's offered by an award-winning author.

"Naming of character in the next book for anyone who gets her back to us! (No, really!)," Lehane wrote.

Anyone who finds or sees the dog can reach out to the author on his Facebook page.
