When the Britannia Theatre's balcony collapses, killing over a dozen people, the fingers point at the architect. He should have known better, should have made it safer, should have done something. Douglas Layton knows the flaw wasn't in his design, but he can't fight a guilty verdict. When he is finally released from prison, he has nothing: no job, no family, nowhere to go. He needs to assume a new identity and rebuild his life. But he soon finds himself digging up the past in a way he never anticipated. If the collapse was not an accident, who caused it? And why? And what if they find out who he used to be?

In 1886 New York, a respectable architect shouldn't have any connection to the notorious gang of thieves and killers that rules the underbelly of the city. When John Cross' son racks up an unfathomable gambling debt to Kent's Gents, Cross must pay it back himself. All he has to do is use his inside knowledge of high society mansions and museums to craft a robbery even the smartest detectives won't solve. But Cross' entire life has become a balancing act, and it will only take one mistake for it all to come crashing down --- and for his family to go down too.

In 1942 Paris, gifted architect Lucien Bernard accepts a commission that will bring him a great deal of money --- and maybe get him killed. All he has to do is design a secret hiding place for a wealthy Jewish man, a space so invisible that even the most determined German officer won't find it. But when one of his hiding spaces fails horribly, and the problem of where to hide a Jew becomes terribly personal, Lucien can no longer ignore what's at stake.
