away.â
âThanks,â Brian said. Obviously, Brian thought, Mr. Potts assumed he and Sean were just another couple of kids with a dumb school project.
âI know you donât allow visitors to carry thingsâeven coatsâinto or out of the museum,â Brian said. âBut how about the people who work here? If they leave with briefcases or boxes, do you trust them, or do you check the contents?â
âItâs not up to me to trust anybody,â Mr. Potts explained. âI just go by the rules. And according to the rules, every container of any kind taken out of the museum has to be examined. No exceptions.â
âWhat about when Mr. Marshall takes your place?â Brian asked.
âHe follows the rules, exactly as I do.â
âDo the museum employees ever go in or out of the museum by the back doors?â
âNever,â Mr. Potts said. âThose doors are unlocked during the day but are used only in emergencies. If anyone tries to open them, locked or unlocked, they set off the alarm system.â
âWho controls the alarm system?â
Mr. Potts looked pleased with himself. âI do,â he announced.
âBut what if an employee stayed after youâd gone home?â Brian was thinking about the burglar alarm system they had at home. âHe could turn off the alarm and reset it, couldnât he?â
âNot in my museum he couldn't!â Mr. Potts answered. âThe curator and I are the only ones who know the combination.â
Brian smiled, thanked Mr. Potts, and then he and Sean left the museum. Outside, Sean reminded Brian about his class field trip.
âGood,â Brian told him. âI know exactly what youâll need to do.â
CHAPTER SIX
B RIAN AND SEAN ARRIVED home before their parents did. Through the windows in the garage door they could see that the garage was empty. Mrs. Quinn usually made it home by five o'clock from her job as a graphic artist at a small advertising agency in town. But Mr. Quinn was just as likely to show up early as late. His hours varied with the work he had to do on each case.
As the boys let themselves into the kitchen, the fax machine in their fatherâs office rang once and beeped.
âMaybe we should see what the message is,â Sean said.
âItâs Dadâs business, not ours,â Brian told him.
âUnless Mom and Dad have been kidnapped by foreign spies,â Sean suggested, âand are being held on a submarine until we come through with the ransom money. How are we going to know if we donât look?â
âYou think someoneâs faxing Dad information he asked for that has to do with the museum thefts?â
Sean grinned. âIt makes more sense than the kidnapping, doesnât it?â
The fax machine beeped again, signaling an end to the message.
âI guess it wouldnât hurt to look,â Brian said.
Brian and Sean raced each other into their fatherâs office and read the fax.
Sean frowned. âThis says that Harvey Marshall was arrested and convicted on a charge of shoplifting when he was eighteen,â Sean said. âBut heâs an old man now,â he said. âWhat he did way back then shouldnât matter.â
âPolice records donât go away,â Brian said. Just then he discovered a legal-size sheet of paper lying on top of a folder on his fatherâs desk. It was labeled âRedoaks County Museum.â It was their fatherâs notes on the case.
âSean,â he said, eyeing the sheet of paper. âItâs not exactly like weâre snooping into Dadâs things if weâre helping him on the case, is it?â
âDad will be glad we helped him,â Sean answered. âAt least, he ought to be.â
Brian began reading his fatherâs notes.
âListen to this,â he said. âHilda Brown recently withdrew most of the money
