An encounter with a blind man ends unexpectedly for Susan Howard. The supposedly helpless man stuns and kidnaps her. The case is handed over by the Home Secretary to Sir John, the head of Scotland Yard. He entrusts Chief Inspector Higgins and Superintendent Lane with the investigation. Their investigations quickly lead Higgins and Lane on the trail of murder, white slavery and blackmail.

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.

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.

After a long time, a circus is back in the area of Tidal Basin and already the strange phantom has reappeared: the white clown! He robbed banks and stores without a system and disappeared without a trace. Lane and Higgins, together with the worn-out journalist Shapiro, hunt for the mysterious culprit in the dense London fog.
