Showing The Templar Treasure by Katherine Kurtz

Deathbed Warning

The old man did not respond at first, but then, all at once, his whole body stiffened. His eyes opened, but what they saw was not Adam or the room beyond.
“The treasure of the Temple!” he rasped hoarsely. “The Seal guards the secret. Adam, it has to be recovered, do you hear me? The Seal has to be recovered!

The Adept . . .
Knight . . . Warrior . . . Doctor . . . Detective . . .
Master of the Hunt!

He is eternal, but so are his foes.

Through countless lives and eras, The Adept has fought the powers of Darkness. Now, as psychiatrist Sir Adam Sinclair, he leads his loyal Hunstmen against supernatural evil in all all its myriad forms.

Now an urgent summons sets the Adept on a life-or death search for the Seal of Solomon, an ancient bronze artifact that can bind–or unleash–the demons of old. Guarded for centuries by the legendary Knights Templar, the Seal has been stolen by a ruthless sorcerer who intends to use it to find the fabled treasure of the Templar Order.

If humanity is to survive, Sinclair must complete the quest to obtain the three Hallows and to prevent his enemy from unleashing an ancient terror into the modern world.
