Yes the HH paedophile yachting club uses the book below to program slaves with - TOMLINSON was programmed with it so one can assume that MARR and DALDRY were programmed with it also.

Looking at where the 'light falls' on that photo - it firstly falls upon a book that I would label as TASCHMAN programming (although there is a photo of the 'reddish haired' brothers in the book below):

ESSEX RIVERS AND CREEKS (1995)

One might also look at the entire selection from the above (SPOTLIGHTED)...

NORFOLK RIVERS AND HARBOURS (1996)
THAMES TIDEWAY (1997)
RIVER MEDWAY AND THE SWALE (1998) - JOHN SAWER's book
IN SEARCH OF THE SAIL (1998)
FAMILY FIELDS (1998)
