Lord Paddington, an honorable member of society, is blown up with a small tennis ball. "Die vier Gerechten" are not of this opinion, however: "Sentenced to death and executed for countless crimes" they leave at the scene. More honorable personalities must die before the perfume Higgins betrays the murderer and exposes the honorable personalities as heads of the organized trafficking of girls.

Strange, rhymed advertisements in the TIMES unsettle three London gangsters - and rightly so, because soon the first of them are killed. The mysterious killer also catches a shady lawyer. Higgins and Lane find out that the key to the crimes is an unsolved diamond heist from jeweler Bolden. It looks like those involved are fighting over the loot. Eventually, it turns out that the "robbery" was actually a set-up insurance scam that Bolden was personally behind and that killed his employee. Shortly before the last survivor is sent to the afterlife, Higgins and Lane are able to confront the "invisible" murderer.
