The Answer to Life, the Universe and Everything

It was a day of contrast on the weather front today. As the clock counts down towards Summer, at least there was some sunshine in evidence.
I caught this lady as she read a phrase book in one of those periods of sunshine.
What language was the subject of the book or indeed what relevant section of the book she was reading I have no idea. So I don't know if she was doing "English to De Lingo" or "Da Lingo to English".
