«The Peacock» by Isabel Bogdan

Take a dilapidated castle in the Scottish Highlands; add a peacock gone rogue, a group of bankers on a teambuilding trip, an overwhelmed psychologist, a housekeeper with a broken arm, and an ingenious cook; get Lord and Lady McIntosh to try and keep it all together; and top it off with all sorts of animals — soon no one will know exactly what's going on.

Selling 500,000 copies, Isabel Bogdan's book is a big hitter in Germany — and now it's coming home to roost.
