Anyway, have a look at the vertical line in the second word that looks like a Roman lowercase f.
It looks like f because it is f!
One of the ways Sinhala used to represent /f/ in English words was fප - a Roman f followed by ප (pa). So I think the text is ඩේවිඩ් කොපර්fපීල්ඩ් ḍēviḍ koparfīlḍ "David Copperfield". Here is the title in a more traditional typeface:
The author is චාල්ස් ඩිකන්ස්ගේ cāls ḍikansgē - I assume -gē is a genitive suffix.
And Sinhala used to do something similar to represent /z/: zස. If anyone has any more examples of zස or fප (photos of books, signs etc), I'd love to see them.
