Further the warning about emails and phone calls, we received a letter, checked the flashy website, but the person signing it is in reality a lawyer in Texas, couldn't find the Spanish one listed.
Googled the address, which is real, but the building derilict.
Phoned the office, asked to speak to letter-writer, not available of course, but the man spoke of our supposed dead relative being a millionairess and we were the only people with the same surname he could find !
Needless to say he said €15,000 would be needed to proceed with the claim....we laughed an hung up.
