From Tatters of the King

Older brother of Alexander Roby. Prominent city banker. One of the three men to sign Alexander's commital papers after the Roby murders. Apparently unwilling to see his brother released.

When interviewed by Dr Bartlett he was belligerent and unhelpful, making it quite clear that he considers his brother to be a dangerous killer. He also suggested that Delia Hartston was in some way involved with the murders.

According to Dr Lionel Trollope's last letter, Grahame hired Vincent Tuck to investigate Alexander's associates.

He is a portly bearded middle-aged man with some resemblance to King George. He looks nothing like his brother.
