Night of Fear (Vintage Paperback) by Peg Kehret

All he has are his wits...

T.J. is all alone babysitting his forgetful Grandma Ruth the night of a murder and robbery at the bank. It's dark and quiet when T.J. and Grandma Ruth go to a neighbor's barn to feed the kittens--and find the menacing stranger inside. He's armed and desperate--and T.J. must protect Grandma Ruth! So he persuades the stranger to take him hostage and leave his harmless, befuddled grandmother behind. T.J. is terrified! His only weapons are his wits as he speeds through the night, prisoner of a madman on a mission of revenge.
