Aurora Teagarden wants a baby, but has recently learned that she can't have one. She and husband Martin haven't really discussed any alternatives, but being surrounded by friends with new babies and friends who are pregnant isn't helping her ambivalence.
So how ironic is it that Martin's somewhat ne'er-do-well niece Regina should show up unannounced on their doorstep with a baby nobody knew she had? And how exponentially is that irony increased when Regina goes missing the next day, leaving the baby behind? And how much harder is it to selflessly take care of a baby when he's not yours, his mother has disappeared, and his father has been murdered with an axe to the head in your driveway?
Martin, strong and silent as usual, and with a potential health issue that he has mentioned but not elaborated upon, insists that they set out for his hometown in Ohio to try to solve this mystery. Roe's character is tested--and sometimes found lacking--by the trials she's forced to undergo in A Fool and His Honey, but in the end, as always, she's strong and brave and loyal.
