"I accidentally gave this book away on Saturday July 25th in a box on the corner of Green and Franklin Streets in Greenpoint," reads a poster in Brooklyn. "The book is extremely important to my wife. It was a keepsake from her mother and is irreplaceable. On the inside cover is a note that reads 'Christmas 1991.' If you happened to pick up this book, can you please get in touch with me?"

"Will send signed copy," Blume tweeted Thursday. "Not the same, I know. Let's hope it saves the marriage."

The next day, Twitter user @reddsauce responded, "I'm the terrible husband!!! Thank you from the bottom of my heart ... marriage saved!!!"

There is no word on whether he was able to track down his wife's book, but Blume said she's "on the case."
