The collapse of the Sasse syndicate came after it wrote a "binding authority" in 1975 that delegated underwriting authority to Florida-based expatriate Dennis Harrison to write property and fire risks through his Den-Har Underwriters agency, even though Den-Har was not an approved Lloyd's coverholder (a fact noticed neither by Sasse nor Lloyd's Non-Marine Association). Den-Har had suspected Mafia links and many of the risks written were rigged: typically dilapidated buildings in slums such as New York's south Bronx, which soon burned down after being insured for large sums.
