Butler Gargery claims the weather in Egypt would help his health. Ramses denies the War Office's request to resume his espionage duties. To add insult to possible injury, the Emerson's feel the effects of WWI German bombs while out to dinner. Given all that conflict, you would think Egypt would be a snap. Only if you are unfamiliar with the workings of the Emerson's.
Conflict seems drawn to Amelia and company like flies to a garbage heap.
This time, there are rumors that Sethos, AKA the Master Criminal did not die, but he lives and has returned to Egypt. If the rumors are not true, it only means another evil doer has donned his title. There are rumors of a big find that is being stolen, and the Emerson's are on the track of the thieves. Many of the series characters make a return appearance. The ending is a rousing free for all, much in keeping with the Emerson's lifestyle.
