I’m still not sure how this book got the title, A Cheeky Chiller.  I had to look up the adjective cheeky to see if I was missing something.  Of course, it’s British slang meaning impudent or impertinent.  And chiller refers to a spine-tingling mystery.  This book is neither.  On each even-numbered page is a clue as to what the animal is and on the opposite odd-numbered page is a photograph of a portion of the animal.  The last photo is a lovely shot of a chimpanze family.  However, the earlier photos are all rather blurry.  Includes a glossary and index.
