The Toff (the 'Honourable Richard Rollison') is faced with danger, but this time from a very unusual source. To prevent him from solving the connection between a body found in the park and a beautiful young girl who appears to be the target for a murder attempt, the killer unleashes an attack using deadly scorpions, snakes and poisonous spiders. Moreover, it is suspected one of 'The Toff's' best and oldest friends is behind the mystery.
