In November 2011, Wishart published the book "The Hunt", co-authored with George London, chronicling the search for two children kidnapped off a London street in 1981 and never seen again. The day the book was published, one of the children made contact with their mother for the first time in 30 years. Lindsay Smallbone, the former husband of George London's wife, sued the authors for defamation in 2013 over the book's description of Mr Smallbone as sexually perverse, voyeuristic and otherwise deviant. The jury found that the material was published recklessly, and awarded NZ$270,000 in damages. The win was short-lived however. On the next working day the judge recalled the verdict and eventually ordered a full retrial after overturning the jury decision. Smallbone appealed to the Court of Appeal and then the Supreme Court but lost both appeals.
