The Tick and Tock of The Secret Old Clock

There's been much ado on Facebook about the 85th anniversary of Nancy Drew http://www.herinteractive.com/2015/04/nancy-drews-85th-anniversary/

So I thought I may as well investigate my favourite author... as a pre adolescent.  Note the following from Nancy Drew's wiki page:

Created by Edward Stratemeyer

Note from his wiki page:

Edward L. Stratemeyer (October 4, 1862 – May 10, 1930) 

The anniversary of his death was yesterday... off by one!!

1959 cover of the revised version of The Secret of the Old Clock, the first Nancy Drew mystery

So the secret of the Old Clock-- it doesn't hold time very well, it's one off on it's tick... or tock!!
