As far as I can tell I am correctly updating the rows in the table but the Challenge Task keeps failing.
I have tried
update phone_book set (first_name, last_name) = ('Mystery', 'Person');
update phone_book set first_name = 'Mystery';
update phone_book set last_name = 'Person';

You're close, and your second try would actually work in practice. But the challenge wants you to to construct a single query that sets both values.
To set multiple values at a time, you can just separate them by commas. Here's a generic example:
UPDATE table SET field1 = value1, field2 = value2;
