I don't see any drop cap in Shadows of Ecstasy; I only see raised caps; it's not the same thing. By the way, the xhtml code employed is not the best.
You have raised caps in Shadows because the first letter has the style "calibre1":

.calibre1 {
    font-size: 1.5em;
    line-height: 1.2
}

while in "War in Heaven" you have nothing. So, in "War in Heaven", in your stylesheet.css, write at the end the following:

.calibre6 {
    font-size: 1.5em;
    line-height: 1.2
}

and in your .xhtml files, enclose the first letter of the first paragraph of the chapter with <span class="calibre6">YOUR LETTER</span>.

For example, in Chapter One you should have the following:

<p class="calibre2"><span class="calibre6">T</span>he telephone bell was ringing wildly, but without result, since there was no one in the room but the corpse.</p>
