To determine the page count of a specific "Call the Midwife" book, you'll need to specify which book you're asking about.
For example, you could ask:
* "How many pages are in 'Call the Midwife' by Jennifer Worth?" (referring to the first book in the series)
* "How many pages are in 'Shadows of the Workhouse' by Jennifer Worth?" (referring to the second book in the series)
Once you specify the book, I can try to find the page count for you.
