In 1850s London, the Great Exhibition is being erected in Hyde Park and, among the crowd watching the dazzling spectacle, two people meet by happenstance. For Iris, an arrestingly attractive aspiring artist, it is a brief and forgettable moment but for Silas, a curiosity collector enchanted by all things strange and beautiful, the meeting marks a new beginning. When Iris is asked to model for Pre-Raphaelite artist Louis Frost, she agrees on the condition that he will also teach her to paint. Suddenly, her world begins to expand beyond her wildest dreams<U+2014>but she has no idea that evil is waiting in the shadows. Silas has only thought of one thing since that chance meeting, and his obsession is darkening by the day.
