Publisher's Summary

An extraordinary fiction debut, Think of a Number is an exquisitely plotted novel of suspense that grows relentlessly darker and more frightening as its pace accelerates, forcing its deeply troubled characters to moments of startling self-revelation.
Arriving in the mail over a period of weeks are taunting letters that end with a simple declaration: “Think of any number…picture it…now see how well I know your secrets.” Amazingly, those who comply find that the letter writer has predicted their random choice exactly.
For Dave Gurney, just retired as the NYPD’s top homicide investigator and forging a new life with his wife, Madeleine, in upstate New York, the letters are oddities that begin as a diverting puzzle but quickly ignite a massive serial murder investigation.
What police are confronted with is a completely baffling killer, one who is fond of rhymes filled with threats and warnings, whose attention to detail is unprecedented, and who has an uncanny knack for disappearing into thin air. Even more disturbing, the scale of his ambition seems to widen as events unfold.
Brought in as an investigative consultant, Dave Gurney soon accomplishes deductive breakthroughs that leave local police in awe. Yet, even as he matches wits with his seemingly clairvoyant opponent, Gurney’s tragedy-marred past rises up to haunt him, his marriage approaches a dangerous precipice, and finally, a dark, cold fear builds that he’s met an adversary who can’t be stopped.
In the end, fighting to keep his bearings amid a whirlwind of menace and destruction, Gurney sees the truth of what he’s become – what we all become when guilty memories fester – and how his wife Madeleine’s clear-eyed advice may be the only answer that makes sense.

Critic Reviews

" Think of a Number is truly unputdownable. Rarely have I read a debut novel that has gripped me as this one has from the first page to the last. This book doesn’t just entertain – it engages you and draws you immediately into the lives of the characters, who are as real as real can be. John Verdon has written a flawless novel about flawed people and he’s written it beautifully. I hope we see a lot more of John Verdon and his smart protagonist, Dave Gurney, in years to come.” (Nelson DeMille)
“John Verdon’s Think of a Number is simply one of the best thrillers I’ve read in a lifetime of thriller reading -- eloquent, heart-rending, deeply suspenseful on many levels, and relentlessly intelligent. The characters live and breathe, the plot is diabolically clever and airtight, and the prose is sublime. Absolutely not to be missed! At one stroke, Verdon establishes himself as a bright star in the thriller firmament.” (John Lescroart)
"Verdon’s protagonist Dave Gurney is one for the ages, and readers everywhere will surely clamor to see this man again. Think of a Number gets full marks from me. And I think it will from you, too. Enjoy." (David Baldacci)

Fresh and Frightening!

If you like Connelly and Coben, you'll love John Verdon. This book is intelligently written, and excitement builds and builds to a very frightening ending! The main character and his relationships develop beautifully over the course of the book. I have been looking for a new author in this genre since my old favorite authors just can't keep up with my audio book habit! It is also my understanding that Mr. Verdon is planning more books with retired NYPD detective David Gurney as the main character. I do not recommend the abridged version... unless you regularly prefer abridged novels.

Terrific: Mystery, Characters, Plot!

I don't need 15 words to say, "Yikes!", "Wow!" or "Wheeee!" Here's the deal. This is the first Dave Guerney novel from John Verdon. It is so gooood I'm afraid to buy the next. Did Verdon save up a lifetime of deviously complex ideas and empty his tank into "Think Of A Number"? Should I even get "Shut Your Eyes Tight"? AAARGH! This is what puzzle psychological murder mysteries should be. "Think Of A Number" ought'a be Webster's definition for the genre.

If you and I share any taste in thriller detective mysteries (see my reviews - I'm tough!) then this… THIS IS A MUST READ, or um… HEAR!

Quibbles… George Newbern's not up to the complexity of these characters and has some trouble differentiating their voices. He's good enough. Oh… and it seems to start slowly… Careful, clues… clues… clues.. here to the process. Enjoy the depth…
