It's the summer of their first year of high school, a time for youthful exuberance in club activities and cultural festivals. The Classic Literature Club, on the verge of disbandment, manages to recruit four new members: the refined young lady Chitanda, the encyclopedic Oreki, the sharp-tongued Mayaka, and the energy-saving youth Houtarou. At Chitanda's request, Houtarou and his partners begin investigating the mystery of the club president's expulsion thirty-three years ago, starting with the preface of an old club publication. What heartbreaking message is hidden in the publication titled "Ice Cream"? This is the first work in the popular youth mystery series "Classic Literature Club Series" by Honobu Yonezawa!
