The 21st Century Predator

Nineteen Killers Who Slipped Through the Cracks

He wore a police uniform and offered women a ride home through the dark streets of a Siberian city. By the time DNA caught up with him, Mikhail Popkov had killed at least 78 of them.

In Angarsk, the deaths of women walking home at night were filed and forgotten. In New Jersey, a nurse moved from hospital to hospital while the drug cabinets logged every dose he drew. In Cleveland, the remains of eleven women lay in and around a house on a street whose residents had complained about the smell for years. On Long Island, a witness description of a killer's truck sat in a case file for twelve years before anyone ran the search that matched it to a Manhattan architect.

The 21st Century Predator follows nineteen modern serial killers across Russia, South Korea, the United States, Mexico, Indonesia, Canada, England and Chile. Each case unfolds in four movements: the facade the killer kept, the method and the blind spot that sheltered him, the investigation that finally closed in, and the motive that drove him. Built on court records, official statements and primary reporting, it shows how DNA databases, CCTV and phone records ended careers that had lasted decades, and how often the evidence had been there all along.

It is also a record of the people who refused to accept the first answer: a caretaker who checked the weekend footage, sisters who pressed detectives until a case was reopened, a refrigeration mechanic who recognized a license plate at a highway rest stop. The victims are named wherever the record allows.

For readers of Ann Rule and I'll Be Gone in the Dark, fans of Mindhunter, and anyone who has listened to Serial and wondered how a case slips through the cracks.

Killing in the Blind Spot

Modern True Stories of Women Who Killed in Plain Sight

On September 30, 2026, Tennessee gave death row inmate Christa Pike two doses of pentobarbital. Six days later she woke in a hospital bed and asked where she was.

A nurse on a neonatal unit in Chester. A former wrestler who knocked on elderly women's doors across Mexico City, claiming to be from social services. A New Orleans police officer who drove back to the restaurant where three people had just been shot, in uniform, looking for the witnesses. An Ontario nurse whose killings surfaced only because she confessed them herself.

Killing in the Blind Spot follows twenty cases from eight countries across four decades. Some of these women killed for years. Others killed once. What they shared was access: a nurse's badge, a lodger's key, a marriage, a bedside. Around each of them stood an institution, or a family, with every reason not to look closely.

Built from court records, inquiry reports and contemporary press coverage, the book traces how each woman came close, how the deaths were missed, and the moment the story finally broke.

  • Nurses and caregivers convicted of turning insulin, bleach and potassium against the patients in their care
  • Six American women sentenced to death, and what their trials reveal about how juries judge women
  • The contested convictions, including Lucy Letby and the Alpine Manor case, where the evidence is still being fought over
  • Where every case stands now, current to October 2026

Written in the restrained, documentary tradition of In Cold Blood. For readers of Ann Rule's The Stranger Beside Me and Charles Graeber's The Good Nurse, and for fans of Mindhunter and Serial.

Cult Killings

From Waco to Shakahola, Modern Prophets and Murder in the Name of Faith

In a forest on Kenya's coast, a former taxi driver turned preacher taught his followers that fasting to death was the road to heaven. By the time the search ended, investigators had exhumed more than 400 bodies.

Outside Waco, a 51-day standoff ended in fire while FBI microphones recorded voices inside asking whether to start it. In Tokyo, a guru's followers carried bags of sarin onto the morning trains two days before police planned to raid his compound. In Utah, a man wrote an order to kill his sister-in-law and her baby on a yellow legal pad and read it aloud to his brothers four months before the killings. In a South Korean factory, detectives searched for a missing businesswoman while she and 31 of her followers lay hidden in a crawl space in the ceiling above their heads.

Cult Killings follows 21 modern cases across 14 countries, from Fall River in 1979 to Shakahola in 2023: doomsday groups, family revelations, sects that sold protection, the Satanic Panic and deaths no court ever treated as murder. Each case traces the facade the group presented, how the deaths happened and why no one stopped them, the investigation, what the courts concluded, and what became of everyone afterward. Built on court records, official inquiries and primary reporting, it shows how often the warnings were given, and how rarely anyone acted on them.

It is also a record of the people who refused to look away: a schoolteacher who followed his son's call into the forest, a husband who walked into a federal office with a hand-drawn map, and three teenagers who saw a fire device fail and told their parents they would not die. Where the record is disputed, the book says so.

For readers of Under the Banner of Heaven and Helter Skelter, and for anyone who has watched a documentary about a cult and wondered how the people inside could not see what was coming.
