Panic Button is the third book in the A Button Box Mystery series by Kylie Logan.
Josie Giancola, owner of The Button Box, has been contacted by Angela Morningside to give her an appraisal on a Charm String. Angela has inherited it from a great Aunt, who has recently passed. Angela feels that the charm string is cursed. Both her great aunt and she have had small kitchen fires, an attempted break in at her house and a major argument with her boyfriend, Larry. When Angela returns to pick up the charm string she is late and appears to be quite agitated. Shortly after she leaves, Josie leaves for the evening starts on a walk and finds Angela straggled, with murder weapon being the charm string. Josie may not believe in curses, but this certainly gives her food for thought. A charm string is comprised of 1,000 buttons, but the police have only been able to collect 999 of the buttons. Since Josie had taken picture of all the buttons she knows which is missing, but doesn't understand the significance of the button.
So with the blessing of her good friend Nev, a Chicago police detective assigned to the case, they head for Advent, IL to attend the wake and funeral for Angela. After a couple visits to Advent, Josie is looking at Susan, the curator of museum that was going to get the charm string. She had been dating Larry before Angela. Larry, the boyfriend, who seems to have something to hide. Marci, who is starting her own museum and who was originally offered the charm string. And Charles, Angela's cousin, who received nothing from the aunt estate.
A very enjoyable and well laid out story. I had to change my opinion more than once on who the murderer was.
I'm looking forward to the next book in the series.
