I took this sentence from *Oxford Grammar*:

> 
> **In the bath was** the biggest spider I had ever seen.
> 
> 
> 

I had always thought that the construction **there + be** is united before reading this example. I would have thought it should be written like this:

> 
> In the bath, **there was** the biggest spider I had ever seen.
> 
> 
> 

However, I'm not sure whether it's a typo that the book has or I've just misunderstood all this time.
