The Silver Ring Mystery of Helen Wells

Vicki Barr is a popular mystery series for girls published from 1947 to 1964. Helen Wells wrote volumes #1-4 and 9-16, and Julie Campbell Tatham, the creator of Trixie Belden, wrote volumes #5-8. Wells returned to write the series, but the last volume, The Brass Idol Mystery, though credited to Wells, is believed to have been written by Walter B. Gibson, the creator and writer of "The Shadow" and sometime author of the Biff Brewster series for boys.

"The Silver Ring Mystery" is the 13th book in the series.
