===============================================================

Here's a screen shot showing the absence of message content:

Yes, indeed, safe mode is something that I should have tried. The problem is so unpredictable and unexpected that I'd overlooked it. The next time it happens(!) I will certainly try it.

Many thanks . . .

I have just noticed in the details issued by Apple "About the macOS Sierra 10.12.4 Update" the line: "Fixes an issue that may prevent content from appearing in Mail messages." This is, of course, precisely the issue that I have. So, it hasn't been fixed!

Must admit to not having re-indexed Spotlight. Trouble is it only happens intermittently and unexpectedly. I'll re-index the next time it happens. I've got around it so far by simply installing a very recent backup, being anxious to get back to a working state.

Thanks everyone for the suggestions and ideas so far . .

I've just discovered, purely by chance and for me at least, that the cause of message content not showing is, ironically, Safe Mode. Within Safe Mode the message content in Classic mode is visible but, after rebooting back into the normal mode, the message content is missing, regardless of the User. Switch out of Classic mode and the content is visible. I've repeated the sequence a number of times with the same result and am personally convinced.

I had tried rebuilding mailboxes, re-indexing Spotlight, removing the ~/Library/Mail/V4/MailData/Envelope Index etc. It was only because I had been in Safe Mode for another reason and immediately returned to read some mail that I made the connection. Fortunately, I have very recent backups. So, what is Safe Mode doing?

The screenshot was not of the mode I normally use but demonstrating that the problem was also showing up in non-Classic mode. Only one email had, in fact, been selected, the colouring showed the conversation. Trusteer/Rapport was the cause of the problem and has been deleted. Thanks for your help.

Trusteer was indeed the root cause of the problem and has been duly deleted entirely. I've not used DiskWarrior for a long time but noticed in the activity monior that a Daemon was running. I don't have Cocktail installed but have deleted TGPro. Many thanks for your help.
