There is something evil afoot in the growing city of Dun Linden, Ireland (1924) where private dicks Michael McCree and Simon Hart have a PI agency. No one has hired them this time, as they find their neighbors and their own tiny spy network in grave danger from a group of thieves who would rather slit a throat than pick an honest pocket; and an old nemesis who has a score to settle with both of them.
When the peril grows too grave for two men to handle, they call on a few trusted friends and some unusual weaponry to help in a case where they are outnumbered—but never outwitted.
The always-edgy partnership of the two investigators also undergoes some twists and turns … of fate and canes alike.
