The new series with the three ???® kids: with proven ingredients – a fascinating case with the three shrewd detectives from Rocky Beach – the reader can now put together his own story. Because: he himself must decide which action sequence he follows, and his decisions determine whether and how the case is solved. This is how it works: at each important turning point in the mystery’s action the reader is presented with two possible alternatives and his selection decides where and how to continue. Accordingly, many different stories and potential endings are possible. Not all paths lead to the case’s resolution. But it’s suspenseful in any case, and a challenge for real good noses. A book to be played with over and over!
