This mystery tale of smugglers and Native American artifacts and a fight against bridges and roads being built on top of someone’s home is fairly standard and quite readable. It reminds me of my beloved Trixie Belden mysteries and of the many mysteries by Helen Fuller Orton and the Boxcar Children series by Gertrude Chandler Warner. This one is not part of a series, but if you like any of Ms. Molloy’s many mystery adventure stories, you will probably enjoy this one.

Thirteen year old twins, Will and Lettie Dennis, and their cousin Jonas Wingate are invited to spend the summer at the old TIbbets homestead with Cousin Mary Peter, whose home is set to be demolished soon so that a bridge can be built from the Maine coast out to Eden Island and Smuggler’s Cove. None of the three really wants to sped their summer in Maine with a cousin they never met, but their parents have asked them to give it a week’s trial. Cousin Mary Peter, a pharmacist, storekeeper, and somewhat eccentric caregiver, assumes that the children are staying for the summer. And as it turns out, Will, Lettie, and Jo find more to pique their interest than they thought they would, including a plan to save the old homestead by having it declared a historical site. The family have always “firmly believed that it [the house] was the very place where the Pilgrims set up a post to trade with the Indians when they came from Plymouth to this bay.” If the children can prove it, the house will be protected.

Published in 1964, the mystery adventure story features free-range children exploring and sometimes doing rather foolish things like stowing away on a smuggler’s boat or taking a leaky boat out into the bay, but all’s well that ends well. (Just don’t try these exploits at home.) Even one of the “villains” of the story is redeemed in the end. It all makes for a satisfying middle grade summer novel. And as I said, it’s a stand alone book, for those who prefer their books free of series entanglements.
