The Haunted Fort was the 44th novel in the original Hardy Boys mystery series. It was produced by the Stratemeyer Syndicate and published by Grosset & Dunlap in 1965. It appeared under the house byline Franklin W. Dixon, of course, and was written by David Grambs, who did a few of the editing/rewriting/updating/simplifying jobs of the earlier books in the series under Harriet Stratemeyer Adams' direction, but this is the only original Hardy novel he produced. The Boys and Chet go to an art camp in New England on Crown Lake at the start of their summer vacation to investigate mysterious goings on at the invitation of Chet's Uncle Jim, who's the chief painting instructor. (I wonder how many uncles Chet had? I'll bet there were a bunch.) There, they meet a variety of suspicious characters and get knocked out a time or two (a common occurrence) and encounter a centuries old mystery from the French & Indian War which they also solve. There are too many characters named for such a short book; they're developed enough to keep straight, and the first time I read it (Nixon was president!) I had to flip back and check to remember just who the named baddie was when he's revealed. Chet takes up painting as a hobby (I wonder how many hobbies Chet had? At least one per book, right?) and wears a beret. (There must've been a law that all artists in the 20th century were required to wear berets. Raspberry not required.) Iola and Callie are present on the first few pages, but after that none of the main support group of family or friends appear. On page one, Iola "dances" off the porch to welcome them and tells them they're just in time for a "homemade hootenanny," and Callie waves a guitar and announces that she "can play two chords." The sexual tension is thick, but Chet calls them away to his bedroom to discuss "murky old mysteries." Iola calls them "sillies," and Callie says they're "meanies," and shortly thereafter a strange black car speeds by and someone throws a papier-mache scalp at them with a note warning them stay away from Crown Lake so, naturally, the game was afoot, and they were off on the chase. It's not a bad story, one of the more enjoyable ones from the 1960s in fact, aside from too many characters, not enough familiar characters for continuity, and a few too many odd happenings. (We didn't need a sea monster as well as a ghost walking across the lake, and the acid in the paint thinner was over the top. But I digress.) Fun, as the back cover proclaims, for "boys from 10 to 14" who like lively adventure."
