Holly Bush Leaf Drop

Question

I have four holly bushes as foundation plantings. One, planted next to the front steps, has lost nearly all its leaves in the past couple of weeks.  The others have no visible damage. Some of the branches are brown and dead looking, others seem viable. Do you have any ideas on what is going on? If it is frost damage/winter kill, then why is only one bush affected?
