Mr. A smiled softly.
*In fact, it is not a suspenseful short story, basically all from the first point of view.
The preface of the introduction is a crude imitation of the nursery rhyme "Who Killed the Mockingbird".
(However, not only is it a bad imitation, but the content has nothing to do with it. Others are interested in suspense, but I am a blame-shifting party, -). )
Intention: A, B, C, D, K and L.
