Death Going Down

This intelligent postwar tale of survival and extortion, obsession and lies, is a classic detective novel from the Argentinian Agatha Christie
 
In the early hours of the morning, a woman is found in the elevator of a plush apartment block on Santa Fe Road, Buenos Aires. She's young, gorgeous—and dead.

It looks like suicide, and yet none of the building’s residents can be trusted; the man who discovered her is a womanizing drunk; her husband is behaving strangely; and upstairs, a photographer and his sister appear to be hiding something sinister. When Inspector Ericourt and his colleague Blasi are set on the trail of some missing photographs, a disturbing secret past begins to unravel.

Set during the aftermath of World War II, when many immigrants left Europe for Argentina—some of them with dark pasts to hide—Death Going Down contains all the ingredients of a classic detective novel.
