19 The argument for the applicant was that the present case was distinguishable on the facts, in that the class of business associates was much wider, and more diffuse, than the groups of persons (characterised as 'small family circles') under consideration in the poisoning cases. Hence, it was contended, the mere fact that all three victims of these fires were members of that class did not give the evidence any particular probative force. We disagree. Not only was each victim a person with whom the applicant had had business dealings, but he was in a current dispute with each of them. In the circumstances, the judge was entitled to conclude, as would the jury as the tribunal of fact, that (in the language of Perry[12]) it would be contrary to ordinary experience for this series of fires, affecting these particular victims, to have occurred by coincidence.
