Riotous Assembly is the debut novel[1] of British comic writer Tom Sharpe, written[1] and originally published in 1971.

Kommandant van Heerden, who has risen to Chief of Police of Piemburg through nepotism rather than merit, is called out to deal with a strange murder case involving the eccentric English spinster, Miss Hazelstone.

A paradoxical anglophile, van Heerden is initially willing to brush the incident under the carpet, until Miss Hazelstone reveals that she and the cook were former lovers (an offence under the Immorality Act) sharing a penchant for transvestism and rubber fetishism.

In his panic to stop the truth getting out, van Heerden places Miss Hazelstone under house arrest, calling in all reinforcements available in order to quarantine the area and places his assistant, the profoundly stupid and bloodthirsty Konstabel Els, on guard, carrying the same elephant gun.

The chaos that follows turns a potentially sensitive political scandal into a full-blown catastrophe, one that van Heerden, his deputy Lieutenant Verkramp and Els must resolve to uphold the 'honour' of Piemburg and apartheid.
