Title: Ingenious courtroom drama
Review: I give it 4 stars as a specimen of the genre, 3 stars in a wider literary context, freely acknowledging that I haven't read much "classic" mystery and have less basis for comparison than some reviewers. I greatly enjoyed the curmudgeonly Sir Henry, and admired his methodical deductions. Without revealing any secrets, I found the Judas Window device pretty ingenious, though requiring a deeper knowledge of home construction than this layman possessed. Still, the plot succeeds very well in its central conundrum of "how" was it done. I found the "who" and "why" a bit less convincing, and felt there was plenty of room for alternative scenarios and suspects employing the same method. Nuff said - I'll try another Carr/Dickson soon and see how it grows on me.
