Display DIV only if post is in most recent specific category

I want to display a DIV atop a post, but only if said post is the most recent in a specific category. In this case, the name of that category is “episodes”. Below is my code… what do I need to bolt onto my IF-statement to make this function properly?

Thanks in advance!

<?php if(in_category('episodes')){ ?>
<div id="latest-ep" class="latest-ep">
<p>Latest Episode</p>
</div>
<?php }?>
