Horowitz is determined to cut ties with Hawthorne but has to turn to him for help when Horowitz is the main suspect of the murder of Harriet Throsby, the Sunday Times critic who gives a scathing review of Horowitz's play, Mindgames. Truth be told, Horowitz (or rather, Horowitz's portrayal of the character Horowitz) can be a bit annoying at times - he's the Watson to Hawthorne's Holmes, but has the ego of the moderately successful author and lacks just enough self-awareness to congratulate himself on his (mistaken) cleverness. Still, this latest edition in the Hawthorne and Horowitz series is entertaining enough.
