Loop only showing most recent post

Hi,

I have a static homepage and need to show just the most recent 4 posts in a section on that homepage. I have the following code, but it’s only showing the single most recent post for some reason. Any ideas? Thanks!

<?php $posts = get_posts();
	query_posts('showposts=1');
	?>

		<?php while (have_posts()) : the_post(); ?>
			<div class="post-home">
				<h3 id="post-<?php the_ID(); ?>"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h3>
				<div class="entry"><?php the_excerpt(); ?></div>
			</div>
		<?php endwhile; ?>
