Christmas Rat

He is one weird Christmas visitor -- his hair and moustache an unearthly white-blond, his voice a gruff rumble. He fills the apartment doorway. From two metal cases he produces what a boy would expect from an exterminator: Toxic roach powders and poisonous fog bombs.
But a crossbow?
Eric is fascinated at first. He''s been bored this snowbound vacation, and has already zapped about a zillion Zergs. Antsy, he''s even sneaked a look at the Christmas presents hidden beneath his parents'' bed. Then Anje Gabrail, this exterminator, appears, talking a little madly about his war against rats -- about killing them.
"The worst," Anje says. And if Eric sees one in the Eden Apartments, he is to call Anje''s twenty-four-hour cell phone immediately. Later that Monday, the fourth day before Christmas, a rat does appear in the building''s basement -- and Eric finds himself suddenly, frighteningly swept into Anje''s vengeful army.
As either partner...or victim.
With only a flashlight.
