Question: If enjambment is continuing to read from one line the the next without a pause, does this mean that liaisons should be made between lines as well?

Example from Hugo’s le revenant:

> 
> La mère dont je vais vous parler demeurait  
> 
> À Blois
> 
> 
> 

I listened to a couple of readings online that did not make the liaison.

Answer: 
There are [three types](https://en.wikipedia.org/wiki/Liaison_(French)#Constraints_on_liaison) of liaisons in French: mandatory, impossible and optional.

The liaison in "*demeurait‿à Blois*" is optional (and rare in modern French), that's probably why you didn't find it in online readings.

If the liaison was mandatory it would have been made even with the enjambment.

This site suggests that liaison should not be made between lines.
