Kell and the Detectives: Book Four (The Aliens, Inc.) by Darcy Pattison

Kell makes a startling discovery: he has zigzag fingerprints.

Worse, Mrs. Lynx and the Society of Alien Chasers know about the fingerprints, and they are on the hunt. Everyone turns detective in this continuing adventure of an alien family from planet Bix, who struggles to make ends meet by putting on birthday parties for kids.

But the stakes are higher than ever because Kell’s mom has just laid a beautiful green egg. With Mrs. Lynx on the prowl, can Kell and Bree keep the egg safe?

Do Historians Act as Detectives?

For History Day, Kell and friends must figure out which teacher created a special graffiti poster. And graffiti just got a lot more fun when a white concrete fence gets a new coat of paint.
