AGATHA CHRISTIE DEATH ON THE NILE

HOW DO I FIND THE THREE IN A ROW DUCKS. I FOUND 2 BUT THATS NOT RIGHT.
HELP.

There is a yellow rubber duckie on the Floor. Second duck has been roasted & is on a platter on the table. Look past the table to the bedspread. Click on the pattern on the side of the spread. That duck is very hard to see!
