Vol.1 - Springald
The Black Museum holds criminal memorabilia from the many cases that have been investigated by Scotland Yard. In this fictional re-imagining of the popular legend, a visitor comes to see a piece of particular interest, the leg of Spring-Heeled Jack. When the curator guides him to the piece, he begins to tell his story of the case of Spring-Heeled Jack, which began in the late 1830s.

The earlier adventures of Spring-Heeled Jack involved an eccentric nobleman named Walter, who used his specially made suit to harass women.

Detective James Rockenfield first suspects Walter, but soon it begins to seem that someone else has taken up the mantle...
