is L. and which is R. You _must_ make the evolutions seem natural.
Thus:--

_Enter from the left_ Miss Devereux. _She stops in surprise at seeing_
Lord Arthur _and holds out her hand_.

_Miss D_. Why, Lord Arthur! Whatever--

_Lord A_. How d'you do? I've just run down to tell Lord Larkspur to--

_Miss D_. He's in the library. At least he--

_Lord A. (taking out his watch_.) Ah, then perhaps I'd better--

[_Exit by door on left._]

_Miss D._ (_to_ Lady L.). Have you seen "The Times" about here? There is
a set of verses in the Financial Supplement which Lord Larkspur wanted
to--(_She wanders vaguely round the room. Enter_ Lord Larkspur _by door
at back._) Why, here you are! I've just sent Lord Arthur into the library
to--

_Lord L_. I went out to speak to the gardener about--

_Lady L_. Ah, then I'll go and tell Arthur--_[Exit to library, leaving_
Miss Devereux _and_ Lord Larkspur _alone_.

And there you are. You will, of course, appreciate that the unfinished
sentences not only save time, but also make the manoeuvring very much
more natural.
