The Devil in the Daffodil Dress

Devon Christian is a man of many secrets, some of them so secret even he doesn't know them, and apparently one of those secrets is his wife.
When a sexy lady with a devil-may-care attitude by the name of Daisy Christian shows up on their doorstep claiming to be Devon's long lost wife, Alex and Devon are immediately suspicious. Not only does Daisy appear to be almost twice as crazy as Devon, but at the same time, Alex and Devon find themselves under attack by a mysterious assailant who's very determined to see them pushing up daisies.
The timing, as they say, is a mite suspicious.
Under a hail of bullets and explosions Alex and Devon must find out who's eager for them to join the choir invisible and unravel the mystery of whether or not Daisy is in fact Devon's true love or just another femme fatale out to help these two investigators get better at taking dirt naps. But more importantly, if she really is Devon's old ball and chain, then where has she been all this time?
