Break-in he'd orchestrated in part of Merseyside (10)

I believe the answer is:

birkenhead

I'm a little stuck... Click here to teach me more about this clue!

'part of merseyside' is the definition.
The definition suggests a singular noun which matches the answer.

'break-in he'd orchestrated' is the wordplay.
'orchestrated' is an anagram indicator (arranged, as music).
'break'+'in'+'hed'='breakinhed'
'breakinhed' is an anagram of 'BIRKENHEAD'.

'in' is the link.

Can you help me to learn more?

(Another definition for birkenhead that I've seen is " Port, say".)
