The 24th Letter

Sean O’Brien series, book #2


A priest hears the confession of a frightened prison inmate, and he learns that a man facing lethal injection in 84 hours is innocent. The lead investigator on the high-profile case was his old friend Sean O’Brien. And now O’Brien has a chance to right a horrible wrong. But he has less than 84 hours to uncover clues to a crime that sent an innocent man to death row.
Appeals have expired and the man will be executed in unless O’Brien can find evidence that points to the real killer. The 24th letter in the Greek alphabet—Omega—may provide the key to uncovering the killer’s identity.
Evidence may not lie, but evil does, and when the original killer comes out of his lair, O’Brien is in a race to save two lives – the man on death row and his own.


“The 24th Letter is very well written with a dark tone. It’s a cross between James Lee Burke, John D. MacDonald and Lee Child.”

– Sons of Spade Mystery Review

“The 24th Letter is so good it ought to be required reading on every adrenaline-addicted, mystery-thriller reader’s must-read list.”

– Book Loons Review

“Even better than A False Dawn and I gave that one 5 stars as well. Very intense. Sean has 84 hours to prove that an inmate on death row is innocent and it takes every minute of it. Reading thrillers, there are often fringe player good guys that are not so good. This was the case here. Figure out who!”

– Jeff Benham (Goodreads reviewer)

“If you like Michael Connelly and his character Harry Bosch, you have to read The 24th Letter.”

-Vero Beach Book Center

“The fast pace and physical smack-downs in The 24th Letter will be perfect for fans of TV’s 24.”

– Kirkus Review

“If you like Michael Connelly and his character Harry Bosch you have to read The 24th Letter. I found myself just totally getting involved with the book and the characters…I could not WAIT to get to the end. TERRIFIC storytelling, and a page turner that you will remember!”

– David English, David’s Booktalk Radio Show

“Warning: don’t start reading Tom Lowe’s new novel, The 24th Letter during a half-hour lunch break unless you have a very understanding boss. Lowe’s straight-forward, fast-paced writing style is addictive.”
