Jealousy, highly unethical business practises and the kidnap of a young woman stretch Gradley's analytical powers, and Esther's astrological skills, to the full. Neville the butler provides both comic relief and human insight to the case.

Furious that a conman is using her astrological skills to target his victims, Esther inveigles Gradley into a plot to unmask the rogue.

An MP's daughter wants to marry a man the MP knows is a murderer – but he can't reveal what he knows without jeopardising himself.

Very much against Gradley's wishes, Esther takes the place of a murdered Brighton astrologer and clairvoyant in order to find out who killed her – thus exposing herself to the same risk.

When Tony Weston is accused of the murder of his father, CEO of a merchant bank, Esther is sure he's innocent – his birth chart proves him incapable of any such violence. With four other possible suspects, finding the real culprit might be tricky.
