The Mystery of the Missing Tea Drinker (Paperback) (ISBN-13: 9780645686609)

It's hard for Alex having a brother like Ollie, especially when their family isn't normal to start with. It's even harder when their father suddenly disappears leaving Alex to unravel the mystery and deal with Ollie's meltdowns. But something's happening with Ollie. He's making suggestions and decisions-more like a partner than a liability. Together he and Alex must decipher and decode clues; elude and bamboozle their pursuers; outrun and outsmart the kidnappers who'll stop at nothing to prevent their schemes being exposed.
