There had to be a wedding.

And it had to be a grand celebration befitting a Fisher Island, Florida, multimillionaire who controls billions from Wall Street to Bermuda, from London to Dubai.

So on a sunny June day two years ago, father and daughter exchanged rings at Westminster Abbey.

They couldn't follow convention by inviting friends or family, and they couldn't make an announcement that they'd eloped.

D. Bruce McMahan, then 65, and his daughter Linda Marie Hodge McMahan Schutt, then 35, pronounced themselves husband and wife on June 23, 2004.

It was their secret.
