instance, Brian and Sean had helped their father prove that it wasnât a ghost who was haunting the Pine Tree Inn. In another case, Brian and Sean had uncovered evidence that called into question the authenticity of a mysterious photograph of âBigfoot.â
From where they sat on the stairs, Brian and Sean could hear the urgency in Mrs. Gomezâs voice.
âThe Redoaks County Museum has what is claimed to be a foolproof security system,â she explained, âbut in spite of all our precautions, two extremely valuable sketches by Leonardo da Vinci are missing.â
âMissing?â said Mr. Quinn. âDo you mean stolen?â
Mrs. Gomez sighed. âYes.â
âIâm familiar with the galleries in your museum, Maggie, but I donât remember any da Vinci sketches,â Mr. Quinn said.
âThe sketches donât belong to the museum,â Mrs. Gomez said. âThatâs what makes the theft even worse. Theyâre from a traveling exhibit on loan from the Metropolitan Museum of Art in New York. Weâve heavily advertised the exhibit, and itâs scheduled to go on display in just one week. If the sketches arenât found by thenâ¦â Her voice broke as she cried, âIâm responsible for the safety of that collection, John! What am I going to do?â
âMaggie,â Mr. Quinn said in his calm, professional private investigatorâs voice. âCall the police about the theft. Theyâll be able to search the museum. Also, theyâll be able to get warrants to search your employeesâ homes. Thatâs something that as a private investigator I donât have the legal right to do.â
âI have called the police,â Mrs. Gomez told him. âThatâs the first thing I did. I also called our insurance company. I was told by the manager of their theft division that ordinarily they would bring in one of their own investigators immediately. But sometimes they prefer to hire private investigators, especially in cases that need to be solved quicklyâlike this one. He gave me your name, John. He knew youâd not only be efficient but would keep the situation as quiet as possible.â
âThen letâs start with a few questions,â Mr. Quinn said.
Brian imagined that his father had pulled out the notebook and pen he always carried with him. A notepad and a pen, his father had explained many times before, are a private investigatorâs most important tools. Brian, who planned to someday become a private investigator, too, pulled his own notebook and pen from a pocket in his jeans.
âTell me the story from the beginning,â Mr. Quinn urged, ânoting exactly when you discovered that the sketches were missing.â
âThe cartons arrived three days ago,â Mrs. Gomez said, âon Friday afternoon. My staff and I looked through them, checked the list, and everything was included. So I shelved the cartons in a special locked cabinet inside our large storeroom.â
âIs the storeroom kept locked?â Mr. Quinn asked.
âNo. Not during working hours. That would be inconvenient. And itâs never been necessary,â she said, âuntil now. I thought the exhibit material was safe, but this evening, when I took out the cartons to decide how to arrange the pieces in the exhibit, I discovered that two da Vinci sketches had been removed from their frames.â
âWas the cabinet broken into?â Mr. Quinn asked.
âNo.â
Mr. Quinn looked up from his notepad. âThen whoever stole the art must have used a key.â
Mrs. Gomez nodded. âMy key, Iâm afraid.â
Mr. Quinn frowned. âHow can you be so sure?â he asked.
Mrs. Gomez was embarrassed. âItâs no secret that I keep the key in my top desk drawer,â she said. âI guess itâs not the safest place I could have thought of, but visitors
