In the heart of a snow-draped Chicago, Christmas is in full swing, but beneath the festive lights and cheerful carols lies a dark and twisted game. Black Love, seasoned detective and former District Attorney, is pulled into a tangled web of deception, greed, and betrayal when a chance encounter with a woman from his past leads him to uncover a mysterious string of crimes linked to a network of Santa Claus street performers.
 
These aren’t your typical jolly Santas. They are skilled con artists, each embodying one of the seven deadly sins—lust, gluttony, greed, sloth, wrath, envy, and pride. Led by a shadowy figure who remains hidden in the background, the group is orchestrating a heist known only as "The Longest Con," a scheme meticulously planned to fleece Chicago’s wealthiest under the guise of holiday spirit.
 
As Black digs deeper, he finds himself crossing paths with old acquaintances—characters whose past encounters with the mastermind reveal pieces of a larger puzzle. Their stories form a mosaic of clues, pointing back to a singular figure who has manipulated them all, weaving a plot that exploits their desires and weaknesses.
 
In a city teetering between the magic of the season and the darkness of hidden motives, Black must navigate old grudges and confront his own inner demons. With the clock ticking down to Christmas Eve, he races against time to unravel the mystery, expose the mastermind, and put an end to the con before it reaches its devastating climax.
 
But as the pieces fall into place, Black begins to suspect he’s been part of the con all along. In a stunning twist, he realizes the game is even bigger than he imagined, forcing him to decide whether he’s willing to risk everything to outplay the ultimate grifter—or become just another pawn in the longest con of them all.
 
This story brings together the high stakes and twists of a classic heist thriller with the complex, familiar dynamics of the Black Love Detective Series, promising a gripping, edge-of-your-seat holiday noir.
