Tuesday Mooney Wore Black

You are cordially invited to play a game... Tuesday Mooney loves a puzzle. So when an eccentric billionaire drops dead, leaving behind a fiendish treasure hunt - open to anyone - to his fortune, Tuesday can't resist. Although she works best alone, she soon finds herself partnering up with best friend Dex (money manager by day, karaoke-zealot by night) and the mysterious Nathaniel Arches, eldest son of a wealthy family who held a long-running feud with the dead man. As the clues are solved, excitement across the city reaches fever pitch - but nothing is as it seems, and the puzzle-within-a-puzzle holds something much darker than a vast fortune at its heart...
