Getting a Way with Murder by Ralph McInerny

"Roger Dowling preferred to relate the events to purgatory. The Divine Comedy was among his three favorite books and Downs was indeed right in thinking of the glutinous events that had dragged him deeper and deeper into trouble in Dantesque terms. Gustave Dore illustrations came and went in the priest's mind, but it was Janski, not Downs, he could imagine up to his neck in ice in the lowest regions of the inferno."
