But just because we haven't seen her female friends does not mean they dont exist in abundance.
But all of this will change in the next upcoming episode with the guest star appearance of Miss Blakes best friend Michelle Rivers who much to Holmes irritation becomes his client.
Miss Blakes fashion and frappucciono "BFF" is to be portrayed by Samantha Rea who has a wealth of commercial, modelling and film experience. This will not strictly be Samantha's first Holmesian outing though as she also previously worked as an Extra on CBS's Elementary.
The first episode in the 4th series is currently still filming and is expected to have a late August release date.
