Is Europe due east of your QTH?

The most critical factor in Beverage placement is to aim the wire in the 
desired direction of reception (or to null out noise in a particular 
direction).

As for length, I have found benefits with wires as short as a quarter 
wave and as low as a foot off the ground. But the longer ones generally 
do better.
