Secret of the Sphinx

La sfinge sorride prima di morire - stop - Londra

Also known as La esfinge sonríe antes de morir, Du grisbi au Caire, Londinon, i Sfinga gela protou pethani, Heiße Spur Kairo-London

Shot on location in Egypt, the story unfurls like an Italian Giallo as a group of people meet under strange circumstances, and one by one they are murdered. Gold is missing so you suspect a thief is trying to cover up his crime but that might be too obvious.
