Clara Gamadge used to be half of a detective team with her husband, Henry, but now that he has died, Clara has to fly solo. Her first case alone turns out to be more complex than she had thought. Fifty years ago, her cousin, Ellen, vanished, and her aunt May suddenly died after ignoring a letter advising her to give up the search for Ellen. Now Clara must sort through the muddled facts and try to make sense of two mysteries: a death and a disappearance. Or was it really two deaths?
