Lincoln Rhyme and Amelia Sachs return to New York City to confront a killer terrorizing couples at their happiest-and most vulnerable.

In the early hours of a quiet, weekend morning in Manhattan’s Diamond District, a brutal triple murder shocks the city. Lincoln Rhyme and Amelia Sachs quickly take the case. Curiously, the killer has left behind a half-million dollars’ worth of gems at the murder scene, a jewelry store on 47th street. As more crimes follow, it becomes clear that the killer’s target is not gems, but engaged couples themselves.

The Promisor vows to take the lives of men and women during their most precious moments-midway through the purchase of an engagement ring, after a meeting with a wedding planner, trying on the perfect gown for a day that will never come. The Promisor arrives silently, armed with knife or gun, and a time of bliss is transformed, in an instant, to one of horror.

Soon the Promiser makes a dangerous mistake: leaving behind an innocent witness, Vimal Lahori, a talented young diamond cutter, who can help Rhyme and Sachs blow the lid off the case. They must track down Vimal before the killer can correct his fatal error. Then disaster strikes, threatening to tear apart the very fabric of the city-and providing the perfect cover for the killer to slip through the cracks.

A traveling businessman is snatched off of an Upper East Side street in broad daylight–or so it appears to the nine-year-old girl who is the crime’s only witness. The perp leaves a token at the site of the kidnapping–a miniature noose. A crime scene this puzzling demands forensic expertise of the highest order. Lincoln Rhyme and Amelia Sachs are called in to investigate.

Rhyme and Sachs’ investigation takes an unexpected turn when a similar kidnapping occurs across the Atlantic in a small town outside of Naples, Italy. The killer’s M.O. is bizarre and frightening. Obsessed with music, the man records the final breaths of his victims, then uses a keyboard sampler to compose an otherworldly tune that is then posted online. The search for the killer will become a complex case of international cooperation–yet not all is as it seems, and soon Sachs and Rhyme find themselves playing a dangerous game with shadowy parties from across the globe.

Amelia Sachs is hot on the trail of a killer. She’s chasing him through a department store in Brooklyn when an escalator malfunctions. The stairs give way, with one man horribly mangled by the gears. Sachs is forced to let her quarry escape as she jumps in to try to help save the victim. She and famed forensic detective Lincoln Rhyme soon learn, however, that the incident may not be an accident at all, but the first in a series of intentional attacks. They find themselves up against one of their most formidable opponents ever: a brilliant killer who turns common products into murder weapons.

As the body count threatens to grow, Sachs and Rhyme must race against the clock to unmask his identity–and discover his mission–before more people die.

The Steel Kiss is available now in the USA, Canada, the UK, Ireland, Australia and New Zealand.

Robert Moreno, an American citizen living in South America, is shot in the Bahamas by a sniper. The killing was commissioned by the U.S. government, who received a tip-off that Moreno was planning a terrorist attack on a U.S. oil company headquarters. But this intelligence was fatally incorrect: anti-American Moreno ordered a protest at the oil company, not an attack.

Lincoln Rhyme and Amelia Sachs are drafted in to investigate. While Sachs traces Moreno’s steps in New York, Rhyme travels to the scene of the crime in Nassau, where he finds himself on a dangerous path trailed by the sniper himself. As details of the case start to emerge, the pair discover that not all is what it seemed. Can they achieve justice and escape with their lives intact?
