Employed by Stockholders' Board to find the French diamonds in ship (6,4)
I believe the answer is:
stable lads
'employed by stockholders' board to' is the definition.
I know nothing about this answer so I can't tell whether this works.
'the french diamonds in ship' is the wordplay.
'the french' becomes 'la'.
'diamonds' becomes 'd' (abbreviation in bridge say).
'in' indicates putting letters inside.
'ship' becomes 'stables' (I can't explain this - if you can you should believe this answer much more).
'la'+'d'='lad'
'lad' put into 'stables' is 'STABLE LADS'.
'find' acts as a link.
Can you help me to learn more?
(Another definition for stable lads that I've seen is " Boys in Baywatch, perhaps".)
