David [slily].  I don’t feel very sleepy yet.

Alick.  Nor me either.

James.  You’ve just taken the very words out of my mouth.

David [with unusual politeness].  Good-night to you Maggie.

Maggie [fixing the three of them].  All of you unsleepy, when, as is well known, ten o’clock is your regular bed-time?

James.  Yes, it’s common knowledge that we go to our beds at ten. [Chuckling] That’s what we’re counting on.

Maggie.  Counting on?

David.  You stupid whelp.

James.  What have I done?

Maggie [folding her arms].  There’s something up.  You’ve got to tell me, David.

David [who knows when he is beaten].  Go out and watch, James.

Maggie.  Watch?

[James takes himself off, armed, as Maggie notices, with a stick.]

David [in his alert business way].  Maggie, there are burglars about.

Maggie.  Burglars? [She sits rigid, but she is not the kind to scream.]

David.  We hadn’t meant for to tell you till we nabbed them; but they’ve been in this room twice of late.  We sat up last night waiting for them, and we’re to sit up again to-night.

Maggie.  The silver plate.

David.  It’s all safe as yet.  That makes us think that they were either frightened away these other times, or that they are coming back for to make a clean sweep.

Maggie.  How did you get to know about this?

David.  It was on Tuesday that the polissman called at the quarry with a very queer story.  He had seen a man climbing out at this window at ten past two.

Maggie.  Did he chase him?

David.  It was so dark he lost sight of him at once.

Alick.  Tell her about the window.

David.  We’ve found out that the catch of the window has been pushed back by slipping the blade of a knife between the woodwork.

Maggie.  David.

Alick.  The polissman said he was carrying a little carpet bag.

Maggie.  The silver plate is gone.

David.  No, no.  We were thinking that very likely he has bunches of keys in the bag.

Maggie.  Or weapons.

David.  As for that, we have some pretty stout weapons ourselves in the umbrella stand.  So, if you’ll go to your bed, Maggie—­

Maggie.  Me? and my brothers in danger.

Alick.  There’s just one of them.

Maggie.  The polissman just saw one.

David [licking his palms].  I would be very pleased if there were three of them.

Maggie.  I watch with you.  I would be very pleased if there were four of them.

David.  And they say she has no charm!
