read more tag in query posts

Is it possible to use the <!–more–> tag when quering posts on a non index page?

I’m using this code

<?php query_posts('category_name=featured&showposts=4'); ?>
<?php while (have_posts()) : the_post(); ?>
<?php the_content('...Read more'); ?>
<?php endwhile;?>

and the read more link doesn’t appear. Pls help
