She is a confident, intelligent woman who appears as a physically attractive 20 year old with dreadlocks. She currently lives in an inherited London townhouse on Beverly Avenue, and is a student at Queen Mary University reading Environmental Science.
She enjoys spicy food and t-shirts with assorted sayings printed on them. She has demonstrated an interest in cars-- especially Nightingale’s Jaguar--and has destroyed several since meeting Peter Grant.
Early Life Edit
Her original, human form was found floating in the brook by the Kingston Vale dual carriageway. During the events of Foxglove Summer she tells Peter she used to run away from her home and go to the river. 
When she joined Peter Grant in the search for two missing girls she is estimated to be 20 years old. However her real age is unknown as genius loci can appear older or younger than their years. She does appear deferential to her older sisters: Tyburn, Fleet, and Effra.
She was half of the hostage exchange, after the events with Henry Pyke, made to ensure peace between Mother and Father Thames as Beverley went to live with Father Thames and Ash went to live in the city. The exchange took place on Midsummer's eve, at Runnymede.
Father Thames Version of Beverley BrookEdit

The following sections contain spoilers for Lies Sleeping, the newest Rivers of London novel.
When Peter enters the memory landscape of London during the events in Lies Sleeping, he encounters a fit blond man with a gold torque at his neck wearing a cloak of beaver pelts. Peter recognizes this person as the Beverley Brook, the son of Father Thames, during a surprise French kiss. As with Lady Ty and William of Tyburn this version of Beverley retains memories from the current time period despite appearing in historical dress.
Beaver Homage Edit
The name of the river 'Beverley' is derived from 'Beavers lay' a place where Beavers live. Beverley Brook was once a habit for a species of Beaver that went extinct in the 16th century. It is likely that the Beaver cloak on the earlier version of Beverley Brook is a direct reference to this animal.
