Books Four, Five, and Six in the John Decker Supernatural Thriller series.

Grendel's Labyrinth- Under a ruined monastery near the quaint village of Clareconnell, a labyrinth of caves hides a dark secret. The remains of Grendel. Defeated by Beowulf and entombed there by the Danes, he has remained hidden for a thousand years, guarded first by warriors, then by monks, and finally by the villagers themselves.

But nothing stays lost forever.

A team of archaeologists is excavating the monastery and searching for his grave. Because Grendel’s bones may hold the key to a medical breakthrough that could change the world.

When John Decker, newly recruited to the shadowy organization called CUSP, arrives in the Emerald Isle to retrieve the bones, he discovers that there’s more to this idyllic village than meets the eye. For Clareconnell has a dark and shameful past, and now that the caves have been opened, the villagers must pay for their sins....

Whitechapel Rising- Jack the Ripper faded into history over a century ago, his identity lost to the ages. Until a work crew restoring a Mayfair home make a shocking find. A secret basement room walled up since Victorian times. The Whitechapel murderer's lair. And inside, a corpse that has waited in silent darkness for over a hundred years. But it won't stay that way....

Within hours of the room's discovery, the body goes missing, and the murders begin anew.

With a violent killer on the loose and the body count rising, John Decker, still new to CUSP, is sent to England, along with seasoned operative Colum O'Shea. Their mission - to stop a ruthless monster from obtaining the one thing that will allow him to escape forever.

As the city huddles in fear and the terror mounts, Decker finds himself in a race against time to catch a hellish fiend smarter than any he has ever faced. Because if he doesn't, the next death might hit a little too close to home.

Black Tide- A secret mission. A horror beyond imagination.

In the last months of World War II, the German Navy premiered a new and terrifying weapon. A submarine of incredible range that could strike anywhere, anytime. And it did, prowling the shipping lanes night and day, and striking fear into the Allies. It was just what Hitler needed to turn the tide of war.

Until it disappeared without a trace.

Now, more than seven decades later, the wreck of a previously unknown U-Boat has been found off the South American coast. A submarine so well preserved that it shouldn’t exist. Eager to learn its secrets, a team of marine archaeologists arrive at a unique seafloor habitat to study the wreck up close. But something has survived on the empty sub. A dark and terrifying presence.

Answering the panicked researcher’s distress call, CUSP sends John Decker to assess the situation. What he finds on the cold and lonely ocean floor is unlike anything he has seen before. A horror from the blackest days of the war. And it doesn’t want them to leave. At least, not alive.
