Agatha Christie's most famous puzzle comes to Lake Oswego for the dark weeks of winter: ten strangers lured to an island, a nursery rhyme, and one guest disappearing at a time. Lakewood Theatre Company stages it as the January offering of its 74th season, and it's an ideal antidote to post-holiday slump. Performances run Thursday through Sunday from January 8 into mid-February, so there's plenty of room to fit in a date night or a mystery-loving friend's birthday.
