Sly the Sleuth and the Sports Mysteries by Donna Jo Napoli

set of three cases all worked out fine. The cases of the Soccer Switch and the Kick Craze and the Basketball Blues. The pairs of words didn’t all start with the same letter, but they started with the same sound: ss, kk, bb. When two words begin with the same sound, that’s called alliteration. Poets use lots of alliteration. We learned that in school just this year.
    This was neat. My first set of three cases all rhymed. And this set all alliterated. There is definitely something poetic about sleuthing.
