Alone in His Teacher's House (Marvin Redpost No. 4)

Illus. in black-and-white. Marvin's friends think he's the luckiest boy in 
the world when his teacher asks him to dog-sit for a week. He gets to be alone 
in Mrs. North's house! But pretty soon it starts to look as if Marvin is not so 
lucky after all...."This title will lure the most reluctant readers, who will 
be as glad to make Marvin's acquaintance as his old fans will be to greet a new 
adventure."-- "Bulletin, Center for Children's Books.
