"Mystery Tour" is a two-part, 60 minute video mystery thriller written by a television crime writer and adapted for ELT by Peter and Karen Viney. It is intermediate level and provides a third stage of video material beyond the level of "A Weekend Away and "A Week by the Sea" (both part of Streamline English Video). It may be used for all classes of students in their third or fourth year of studying English, as an accompaniment to any intermediate level course and for all learners wanting to revise their English in small groups or on their own at home. "Mystery Tour" consists of two 30 minute video cassettes, an Activity Book for students and a Video Guide for teachers. The highly illustrated Activity Book contains before and after viewing activities for each episode, combined with storytelling from photographs and exercise material designed to provoke practice and extension of the language being taught.
