Barnabas Tew and the Case of the Missing Scarab by Columbkill Noonan

Barnabas Tew is a Victorian detective who imagines himself to be just like Sherlock Holmes. Sadly, he is not nearly so clever as his idol, and tends to make a dreadful mess of things. Imagine his surprise, then, when he and his assistant, Wilfred, are attacked by a mummy in a museum and wake up to find themselves not only dead, but in the Egyptian afterlife! Can Barnabas do a better job of things here than he did in London?
