Fiona, who adopted a bee in Fiona's Bee (1975), now takes up with a fleabitten old dog and ends up with a flea on her arm. Fiona has just refused to go to the circus--animals shouldn't be in cages--so we know she's compassionate. What, then, to do with the flea, who will die if she flicks it off? And what to do with the dog, whose condition appalls her unsympathetic parents? With friend Howard's help, Fiona finds a neat solution: a man who runs a flea market likes the idea of an old-time flea circus as an attraction; an old woman met poking through a trash can knows how to train fleas, and she'll also take the dog: ""Every good show needs a barker."" This is a bit more contrived than Fiona's Bee, but once more Keller gives us an under-the-skin sense of a kid alone, and a quick solution with a little more wit than many that pretend to be realistic.
