Irby Walker & the Curious Case of the Covert Cows

Cow licks have been springing up on children all over the hospital. The only solution is that cows have been sneaking in at night to lick the children in their sleep. Their motivation remains unclear, but only one man can stop them: Irby Walker, the hospital security guard. He is on the case!

Written for children ages two to five, the book details Irby Walker's investigation around the hospital. Beware, though, cows can hide in plain sight. Especially if they're dressed as ninjas!
