At a glitzy London celebration, the chairman’s wife drinks a champagne toast--and dies minutes later. Was it suicide? Overdose? Or murder? Given the high profile of the case, MI5 is called in to investigate. Enter Geoffrey and Catherine--not even their family know that they are top undercover agents. There’s no shortage of suspects in this glamorous world.
