The season ends with Eliza standing on the roof of her agency, looking out over a smoky London. Blake is downstairs waiting to take her to a new case. Ivy is baking a cake in the kitchen. The Duke’s desk is gone.
The chemistry between Phillips and Durant-Pritchard is electric but entirely different from her dynamic with Martin.
