Conni's neighbor, Mrs. Sandulescu, has been burgled! Not much was stolen—just some money, a few pieces of silver cutlery, and a small picture that hung in her living room. But that picture has been in the family for so long that Mrs. Sandulescu desperately wants it back. The police are investigating—and of course, Conni is helping. This is another case for the four detectives and their sniffer dog, Nicki. They need to find the picture!.
