'Now please confess at once,' she wrote, 'that it was because I
witnessed your promise to tell me all about him, that you sent that
letter, otherwise you wouldn't have thought of writing to a poor silly
girl. And wasn't it interesting! I told you he was a wonderful man,
and you see how he has paid you already for the little kindness you
showed him. Why, in all probability he saved your life! And now I
want you to do something else for me; I want you to send me his
photograph. I have conjured up a picture of what I think he is like,
and I am anxious to see if I am right. Aren't I taking a lot of
liberties with you! But you see I like you,--I do really. I fell in
love with you when you came to Granitelands with Sir Roger Granville
that day. Oh, no, there's nothing romantic about it, I can assure you!
But you looked so kind, and trustworthy, and strong, that I took to you
from the very first moment. Father tells me I am wrong to take violent
likes and dislikes to people at a first meeting; but I can't help it, I
am made that way. Of course you are not a bit attractive in the

flatter. Besides, you're old. Now don't be angry. Every girl looks
upon a man who is getting on for forty as old. But I am fond of you
all the same. There's a sense of security about you; I am sure I could
trust you, just the same as I trust my father.

'Send me that photograph of your friend as soon as you can, I am
anxious to get it. I am awfully busy here in this hospital, and there
are such a lot of wounded men, many of them with a limb shot off. Do
you know, I am tremendously interested in a poor Tommy who has lost
both his legs. Horrible, isn't it! But he's the most cheerful man in
the place, and keeps us laughing all day long.

'He wrote a letter to his mother yesterday, and told her to get him a
pair of patent-leather dancing shoes.

'You will be sure to be careful, won't you?--I can't bear the idea of
anything happening to you; and although I know you are old enough to be
cautious, and not to take foolish risks,--that is, in the ordinary
way,--I am sure you are one of those men who forget everything like
caution when you are aroused. This is awfully silly, isn't it? so I'll
stop. I command you, write me at once, and do as I tell you.

'Yours obediently,

'LORNA BOLIVICK.'

I answered this letter at once. I was in a dug-out at the time,
