This book is about Erik Granger and the Dopple girls, Saskia and Sadie. Erik is the only boy at Dunstan's a school for orphans. He is supposed to go go to sleep but defiantly stays up and stumbles upon burglars in a secret passage stealing special artifacts from Lord Gervez's house, which is next door to Dunstan's. In the morning as he serves breakfast to the girls he tells Sadie and Sakia about the burglars and informs them that the burglars are returning again that night to get the last of the artifacts. The Dopples and Erik sneak out after lights-out and watch the burglars. They hide but Saskia was too slow and didn't know that the burglars were coming back down the tunnel and has to hide inside a sarcophagus that the burglars were stealing. The burglars do not know that Saskia is in it and they take the sarcophagus to their lair. Sadie and Erik follow Lord Gervez into his home through the tunnel and find out that someone named Indigo Moon made all the houses and connected them with tunnels that only he knew about. The tunnels were being used to rob all the homes on that street. A reporter for the Times (and secret detective) Dorcas Potts interviewed the gang the afternoon the day Saskia was kidnapped. Now the gang needs to work together to find Saskia and stop the burglars.I liked this book because it had segments of the book in comic book and it looked cool because it helped you imagine what the characters in the book looked liked and what was going on in the book. Like when it did not tell you what type of car or school uniform it showed you in the comic book segments. I also liked the mystery part and adventure parts of the book because I like books that have a mix of thrill and a mysterious side. I think you will like the book.
