What am I doing wrong in this SQL Server 2005 case statement?

Consider the following code, which works:

SELECT
	CASE AuditKey
		WHEN 1 THEN 'Foo'
		ELSE 'Bar'
	END
FROM
	Audit

Now lets say I want to test for when the audit key is between 1 and 10. I've tried various bits of syntax but all say 'Incorrect syntax near the keyword 'BETWEEN''. Here are some of my attempts:

SELECT
	CASE AuditKey
		WHEN BETWEEN 1 AND 10 THEN 'Foo'
		ELSE 'Bar'
	END
FROM
	Audit

SELECT
	CASE AuditKey
		WHEN AuditKey BETWEEN 1 AND 10 THEN 'Foo'
		ELSE 'Bar'
	END
FROM
	Audit

I must be missing something obvious, any ideas?

Yup it's an int. This is an example, I've tried it on various number values on different tables with the same error!

Bingo, that's what I'm looking for. Many thanks.
