A Question of Time — Fred Saberhagen

He was once called DRACULA but in our day he is known by many strange names....

In 1935, Conservation Corps worker Jake Rezner meets a beautiful and mysterious young girl in the Grand Canyon. She leads him deep into the rocks, to a bizarre sculptor named Edgar Tyrell. Soon Jake finds himself lost in time; unable to return.

Almost 60 years later private detective Joe Keogh has been hired to locate a missing girl -- the great niece of Edgar Tyrell. But Tyrell is nosferatu , and he would sculpt in the sands of reality itself. So Keogh must call on Mr. Strangeways, An Old Friend of the Family and Lord of the Vampires, to battle an undead menace from beyond time!
