Another outing for Peter Grant and the Folly – that branch of London’s Met Police which looks after cases which show signs of ‘weird bollocks’ – i.e. Falcon cases, anything to do with magic and the supernatural. Peter is now on the brink of becoming a father, His wife Beverly, a minor river goddess, is carrying twins, due any day now. So, of course, Peter gets involved with a double murder that might or might not be something to do with seven linked rings and the Spanish Inquisition. Which, of course, no-one expects… Yes they manage to get that joke in, plus a few Dr Who easter eggs (Mr A has written for Dr Who.) Expect the usual magical police procedural plus the return of one-time friend, now magical antagonist, Lesley, plus an added helping of the Angel of Death, or at least AN angel of death.
