The first book I read of this author but it was fascinating.the play of disguise by the main protagonist hannay to evade the german spies and the police(as he got hint of the plan of german spies to steal british plans)and the mystery of the 39 steps kept me glued till the end.the situations created by the author to highlight hannays intelligence, the present decisiveness and courage to tackle any dire situations can be given high praise.overall I recommend reading this book because I think will not be disappointing.
