Secret Adversary 75% Agatha Christie

British pluck. Tommy thinks Tuppence is dead, but he soldiers on bravely.  She, earlier, thought he was dead, but . . .  The missing documents are still missing. Julius (the American) is looking more and more like Mr. Brown.  A photo Antoinette, the French maid at the place where Tommy was nearly killed, shows up in Julius's drawer. Plodding Tommy just might save the day.  Great fun, but the characters aren't quite real. We're supposed to believe Tommy and Tuppence, without admitting it, are truly and deeply in love. Yet when one thinks the other dead, it's a bit like they've lost a favorite pen.  The plotting of the story, though, is quite amazing--I'm assuming AC can pull it off.  My guess is that Julius is, in fact, Mr. Brown.
