The Snake, the Crocodile and the Dog

I found this one more gripping but less amusing than usual. The mystery element is as usual contrived and over-complicated, but at least I didn't find it tedious this time.

The story is set mostly in Egypt, but Ramses and Nefret have been left behind in England with Walter and Evelyn, so for amusement we mostly have to rely on the occasional but verbose letters from Ramses, bringing his parents up to date on events back home.

The Master Criminal Sethos (whom I dislike) returns in this story, but he remains either offstage or well disguised throughout, so at least we don't have to deal with him in his own persona.

After a blow to the head, Emerson suffers from amnesia for a large part of the story, forgetting his marriage to Amelia, so for a while they're back to dealing with each other as near-strangers again.
