The Patrone Case

"Janet is happy to help William Chalmers, the owner of Doveby Dale’s antique shop, interview a few potential employees. She and William are friends, although William often hints that he has romantic intentions. Regardless, it makes a nice change for Janet from the day-to-day running of the bed and breakfast that she shares with her sister, Joan.
The three candidates for the part-time job are less than stellar, though. When a brick gets thrown through William’s window the day after the interviews, Janet can’t help but wonder if one of the three was involved."
