<h2> <SPAN name="article32"></SPAN> The Watson Touch </h2>
<p>There used to be a song which affirmed (how truly, I do not
know) that every nice girl loved a sailor. I am prepared to
state, though I do not propose to make a song about it, that
every nice man loves a detective story. This week I have been
reading the last adventures of Sherlock Holmes--I mean really
the last adventures, ending with his triumph over the German
spy in 1914. Having saved the Empire, Holmes returned to his
farm on the Sussex downs, and there, for all I mind, he may
stay. I have no great affection for the twentieth-century
Holmes. But I will give the warmest welcome to as many
adventures of the Baker Street Holmes as Watson likes to
reconstruct for us. There is no reason why the supply of
these should ever give out. “It was, I remember, at the
close of a winter’s day in 1894”--when Watson
begins like this, then I am prepared to listen. Fortunately,
all the stories in this last book, with the exception of the
very indifferent spy story, are of the Baker Street days, the
days when Watson said, “Holmes, this is
marvellous!” Reading them now--with, I suppose, a more
critical mind than I exhibited twenty years ago--I see that
Holmes was not only a great detective, but a very lucky one.
There is an occasion when he suddenly asks the doctor why he
had a Turkish bath. Utterly unnerved, Watson asks how he
knew, to which the great detective says that it is as obvious
as is the fact that the doctor had shared a hansom with a
friend that morning. But when Holmes explains further, we see
how lucky he is. Watson, he says, has some mud on his left
trouser; therefore he sat on the left side of a hansom;
therefore he shared it with a friend, for otherwise he would
have sat in the middle. Watson’s boots, he continues,
had obviously been tied by a stranger; therefore he has had
them off in a Turkish bath or a boot shop, and since the
newness of the boots makes it unlikely that he has been
buying another pair, therefore he must have been to a Turkish
bath. “Holmes,” says Watson, “this is
marvellous!”</p>
<p>Marvellously lucky, anyway. For, however new his boots, poor
old Watson might have been buying a pair of pumps, or bedroom
slippers, or tennis shoes that morning, or even, if the
practice allowed such extravagance, a second pair of boots.
And there was, of course, no reason whatever why he should
not have sat at the side of his hansom, even if alone. It is
much more comfortable, and is, in fact, what one always did
in the hansom days, and still does in a taxi. So if Holmes
was right on this occasion, he was right by luck and not by
deduction.</p>
<p>But that must be the best of writing a detective story, that
you can always make the lucky shots come off. In no other
form of fiction, I imagine, does the author feel so certainly
that he is the captain of the ship. If he wants it so, he has
it so. Is the solution going to be too easy! Then he puts in
an unexpected footprint in the geranium bed, or a strange
face at the window, and makes it more difficult, Is the
reader being kept too much in the dark? Then a conversation
overheard in the library will make it easier for him. The
author’s only trouble is that he can never be certain
whether his plot is too obscure or too obvious. He knows
himself that the governess is guilty, and, in consequence,
she can hardly raise her eyebrows without seeming to him to
give the whole thing away.</p>
<p>There was a time when I began to write a detective story for
myself. My murder, I thought, was rather cleverly carried
out. The villain sent a letter to his victim, enclosing a
stamped addressed envelope for an answer. The gum of the
envelope was poisoned. I did not know, nor did I bother to
find out, whether it was possible, but this, as I said just
now, is the beauty of writing a detective story. If there is
no such quick-working poison, then you invent one. If up to
the moment when the doubt occurs to you, your villain had
been living in Brixton, you immediately send him to Central
Africa, where he extracts a poison from a “deadly
root” according to the prescription of the chief
medicine-man. (“It is the poison into which the Swabiji
dip their arrows,” you tell the reader casually, as if
he really ought to have known it for himself.) Well, then, I
invented my poison, and my villain put it on the gum of a
self-addressed envelope, and enclosed it with a letter asking
for his victim’s autograph. He then posted the letter,
whereupon a very tragic thing happened.</p>
<p>What happened was that, having left the letter in the post
for some years while I formed fours and saluted, I picked up
a magazine in the Mess one day and began to read a detective
story. It was a very baffling one, and I really didn’t
see how the murderer could possibly have committed his foul
deed. But the detective was on to it at once. He searched the
wastepaper basket, and, picking an envelope therefrom, said
“Ha!” It was just about then that I said
“Ha!” too, and also other things, for my
half-finished story was now useless. Somebody else had
thought of the same idea. But though I was very sorry for
this, I could not help feeling proud that my idea made such a
good story. Indeed, since then I have fancied myself rather
as a detective-story-writer, and if only I could think of
something which nobody else would think of while I was
thinking of it, I would try again.</p>
