TALE OF THE WITCH DOLL
THE VANISHING HOUSEBOAT
DANGER AT THE DRAWBRIDGE
BEHIND THE GREEN DOOR
CLUE OF THE SILKEN LADDER
THE SECRET PACT
THE CLOCK STRIKES THIRTEEN
THE WISHING WELL
SABOTEURS ON THE RIVER
GHOST BEYOND THE GATE
HOOFBEATS ON THE TURNPIKE
VOICE FROM THE CAVE
GUILT OF THE BRASS THIEVES
SIGNAL IN THE DARK
WHISPERING WALLS
SWAMP ISLAND
THE CRY AT MIDNIGHT
