MONTALBANIAN LITERATURE

I am reading Excursion to Tindari, as stage two of my Camilleri/Montalbano marathon read.

In the book Salvo Montalbano as well as investigating the murder of a young man and the disappearance of an elderly couple, is reading Manuel Vazquez Montalban's crime novel The Buenos Aires Quintet.

Montalbano reading Montalban, is there a nicer word than incestuous for such an event?
