How would Sherlock Holmes look under a door

[MelissaEliza1]

I am currently starting a illustration project for university and one of my major characters is Sherlock Holmes.

 

I was currently wondering in all versions of Sherlock, what would he use to look under a locked door of a well lit room, that he could not open.
He can not remove the door, unlock or open the door, or look through any other windows, cracks or holes.
Simply what kind of equipment would he use to look under the door and into a room?

 

This can be from the original literature or any of the alternative versions.

 

Thank you

One of those surgical cameras?  They should be thin enough to ease through a key hole or under the door.

He could use a thin mirror and slip it under the door. If there was another room, next door, again he could use a mirror by opening a window or if buildings over the road, use the reflection of those windows to see what was going on.

Somewhat similar to Fox's surgical camera (which I consider a great idea), I think there are fiber-optic periscope-type things that would be plenty thin enough to poke under a door.

 

How tall is the crack, by the way?  And how wide?  And how thick is the door itself?

For Sherlock it will mean according to his character and personality he'd break-in!

Probably, but not until he was able to ascertain the room before doing so. No contaminating the crime scene don't you know.

As did Leonard and Howard when they tried to find out where in the apartment Sheldon was. Then Leonard crawls through the apartment and got busted by Penny.

 

(Sorry. Couldn't resist).

I'd have said a mirror, or he'd look at the shadows on the floor boards cast by the sun/moonlight probably!

For the purposes of the assignment, that answer would probably my get her a big fat 0.

Well, it's a little late, but you made me curious and just tried it out: what you need is a small mirror.

 

 

the vertical figure is the door, the horizontal - the floor. the blue one is the mirror. If you hold it with one edge to the ground and move it like in the picture looking from above (the funny symbol is an eye looking down) you can achieve surprisingly good view from the other side.

The mirror should be possible flat, the door not too thick (ca. 20 mm in my case) and the crack should have 5-7 mm.

 

Have I won something?

I do believe you're the first person who's actually tried out their suggestion -- which is probably the simplest one so far -- to say nothing of supplying a diagram.  That's gotta be worth something.  So how about this:

Actually, what made me read this thread first was the title. I read it like "How would Sherlock Holmes look like under a door".

  Oh, that's too cute!

The sirurgical camera sound good, but it would be too easy to get the wrong angle and just see a piece of flor. Maybe a small mirror smartly attached to the camera would give better results.

 

I personaly think that he would't loose his time trying to see what he can, but would figure out a way checking what he would like to check. If he is looking for someone he can try to feel the vibration of the flor, or to listening it through the door. Or even by smell.

I think there's a good possibility he would simply open the door.
