Fourth in the series and a departure from precedent in a few ways. Book Virgil now inhabits a world where Movie Virgil exists - and he recognizes and jokes about such - but no even minor wealth has accrued to him because of it, which feels odd when Tibbs discusses on a few occasions the limits of a policeman's salary. Additionally, It's unclear whether Virgil is the lone 'real' fictional detective here, since Charlie Chan, Sherlock Holmes, and Nero Wolfe are all mentioned in passing and none is explicitly a reference to a literary figure - CC is even said to be alive and retired in Hawaii - which could be read as a joke, or a bit of cheeky world building. We'll see what future volumes bring.
Secondly this is the easily the longest volume, and the first with dueling storylines, each of which could have been built into its own tale.
Finally, while its nice to get VT a love interest, she is the least interesting of the new characters, which could be excused as the limits of a foreigner with limited English skills to connect wit han audience, but the other character with a similar background is three times as interesting while appearing in less than a third of the story.
