Morgan Stark, a brilliant doctor, is stunned when his hospital’s resident is found murdered, clearly the work of a serial killer. The FBI needs Morgan, with his medical expertise, to decipher the subtle medical clues that will lead to the killer—but can he crack the code before it’s too late?

“A brilliant book. I couldn’t put it down and I never guessed who the murderer was!”

—Reader review for Only Murder

TOO LATE is the debut novel in a new series by #1 bestselling and critically acclaimed mystery and suspense author Rylie Dark.

Morgan Stark is a renowned surgeon, acclaimed by his colleagues for his brilliance as a diagnostician. But when his close friend and protégé resident is murdered, Morgan feels compelled to help the FBI decipher the trail of medical clues and bring the killer to justice.

FBI Special Agent Quinn Carter, 28, a rising star in the BAU, equally esteemed by her colleagues for her brilliance and determination, is not used to turning to a doctor for help in solving crimes. This unlikely partnership, though, may just surprise them both.

Yet as brilliant as this team is, they are up against a diabolical mastermind who will stop at nothing to outwit them.

And going too deep into his mind may just undo them both.

A cat-and-mouse thriller with harrowing twists and turns and filled with heart-pounding suspense, the MORGAN STARK mystery series offers a fresh twist on the genre as it introduces two brilliant protagonists who will make you fall in love and keep you turning pages late into the night.

Books #2 and #3 in the series—TOO CLOSE and TOO FAR GONE—are now also available.

culprit at all… Already pre-ordered the second!”
