sorry I know this photo is awful. I’ve noticed this crack under some wallpaper in an upstairs bedroom. I’ve read step cracking is a worry. It’s about 10 inches from the top of the wall and to the right is a window. The plaster to the right does sound very hollow if you tap it. House is 1960s and I think it’s still original plaster. This is an end wall that does get a fair bit of sun. I’ve peeled back the wallpaper a little and can see a tiny crack but it does stick out a bit. I can’t see a cracks in the wall outside.

You could remove the wallpaper and inspect and keep under review any crack, but it’s difficult to tell if that brick has been disturbed or it’s just movement of the plaster.
 
I’ve pulled the wallpaper back a little and this is underneath

I was concerned that maybe the brick had shifted for some reason and that’s what had caused the cracks/ brick outline to show. Husband has pointed out that it looks like the crack underneath the paper has been painted so it’s probably been there long before we moved in. Do you think these are normal cracks for an older building?

Yeah, it is quite common in older buildings.

(I am a decorator).

If the wall is 9" thick, and there are no visible cracks outside (in the bricks and mortar), I really wouldn't be concerned.

If you want, I can offer advice but I am on pint 4.5.6 and need to be up early
