A destination wedding in Slovenia ought to be a joyous occasion for Palmer, Stuart and Gina as they gather together to celebrate their old friend Alice's forthcoming nuptials, but something is amiss in sunny Ljubljana, with an AWOL painter and a string of mysterious and surely unrelated suicides leading them towards the a centuries old work of art that seems to be laced with dark superstition and evil. Where is the troubled artist Alojz? Are these separate deaths part of a bigger puzzle? Why is Alice's chief bridesmaid, Miranda, so objectionable? Will Palmer's team solve the case in time so that Alice may happily walk down the aisle? What untold dangers lurk in the Art of the Dark?
