The location of the next clue is hidden inside some text. The hunter has to look for and correct errors in a sentance. The corrections they make will lead them to the next clue.

For example "everybwdy lomes a trpasure hult" spells out "oven":

everybwdy lomes a trpaure hult
everybOdy loVes a trEasure huNt
O..V..E..N
OVEN

Alternatively, if you would like to make it easier you could simply put in double letters instead of incorrect letters:

everyboody lovves a treeasure hunnt
o..v..e..n
