Death of a Bean Counter by Sandra Balzo

Maggy loves their coffee house and how successful they are.  But when her partner tries to talk her into selling luxe espresso machines, she's not sold on the idea.  Why take customers away from themselves?  It gets worse when her barista is arrested onn suspicion of murder...

Severn House and Net Galley let me read this book for review (thank you). It will be published April 7th.

Maggy didn't even know Amy was dating the victim.  Then she finds out she was the last person to see him alive and they had a huge fight before she left.  He surprised her with a marriage proposal, very public, and she said yes rather than embarrass him in the restaurant.  But once they got back to his place, she gave him the ring back.  They'd only been dating three weeks, she wasn't ready to  commit to anything yet.  There were witnesses to their shouting match.  Amy swears she didn't kill him.

Then they learn he was stealing money from his customers at the bank.  That opens up a lot more suspects.  Even his children might have done it because he was going to change his will and give his house and assets to Amy.

Maggie's boyfriend is the sheriff but he's not sharing much with her.  She decides to investigate herself.  But she better be careful...
