Mystery in the Flooded Museum — Margaret Goff Clark

As Susan Drummond begins a summer volunteer job at the Fort Pitt Museum, a flood threatens the Pittsburgh area and an immensely valuable wampum belt disappears.

Who stole the wampum? Was it the proud young Indian, Frank Tallpine, or possibly Pearl Quinn, the kooky photographer? Or any of the many people who work in or visit the museum?

Even Susan is a suspect, as she finds out to her shocked surprise. It makes her feel better when Eric, another student worker, shows his interest and faith in her.

But not even Eric can help her when Susan, left behind in the flooded museum, finds herself on the track of the thief.

In an exciting climax Susan realizes that only she can save herself from a terrible death.
