A Missing Mom and Mutt Munchies - A Maggie May and Miss Fancypants Mystery, #4

Maggie May Carver is done with murder. She's sworn that if she finds another dead body she's just going to step right over it and continue on her merry little way. But when a little boy with sad eyes and freckles shows up asking her to find his mom, she just can't say no. Once more Maggie is in the thick of things, this time trying to find a little boy's mom in time for his birthday with the help of her cranky grandpa, the handsome local cop, and his charming but criminally-inclined brother.
Oh, and of course, her incorrigible Newfoundland, Miss Fancypants.
