"Sixth Sense" is a strange book as Kate Calloway, who up to now has been mostly a traditionalist in terms of the Cass James settings, brings in the woo-woo element - telepathy, clairvoyance, premonitions, the whole gamut!
It's probably best not to read "Sixth Sense" before the previous books in the series - by this stage there is just too much baggage.
Maggie Carradine, Cass's ex, is back in town and so far Cass has managed to avoid the low-down cheating, etc., etc. Cass is definitely not the type to forgive and forget, at least not in any hurry. She's excellent at carrying a grudge and nursing a grievance.
Maggie, however, is in trouble - she's having dreams either of events as they happen or as they happened. There's been two murders so far and she's seen the events through the eyes of the murderer. And there is a link to a therapy group, Victims of Abuse, which Maggie has begun running. Both murder victims were among those who abused members of the group.
As Cass begins to investigate she, too, begins to have strange dreams - they appear to be the memories of an abused child. Are they real, Cass never really doubts that they are. Are they true or fictitious?
As with the previous book the ending sees the murderer revealing themselves just as Cass is discovering who it is. To be honest, how Cass finds out just didn't work for me, far too convenient and unbelievable.
Six books in I am enjoying living with Cass's life, probably more so than how her mysteries work out. Each book is like meeting up with an old friend and catching up. Though I can't help but imagine that Cass's greeting would be along the lines of "Still Straight?"
