La morsa bianca

The construction of an amusement park in Naples brings to light the horrors of Raimondo di Sangro's ancient alchemical laboratory. The experiments of the Prince of San Severo and his eighteenth-century anatomical machines will constitute a more than current threat to the Detective of the Impossible. So, with "The White Clamp", an adventure begins that will lead Martin Mystère to deal with unreasonable downpours, snowfalls and various bizarre weather conditions.
