thief should one come out of one's house...

[Dawood Usmani]

Dear teachers!
Is the use of should and but correct in this text? I've taken it from a book.
"Water is available outside one's house. But there is a threat of one getting killed by an enemy or thief should come out of one's house."
Best regards!

Yes, it's fine.

The use of 'should' in this sentence is an example of the subjunctive form. It's used instead of the more common first conditional structure. It isn't often used in spoken English, but you sometimes find it in more literary forms of written English. Here are a couple more examples:

'If you should see a copy of this book in the shop, please buy it for me.'
'Please do not hesitate to ask for assistance from reception should you have any problems during your stay'
