And that, let me assure you, is not a waste of time. Public institutions throughout the fifty states provide food and clothing and shelter for lads who don’t ring the bell first. And it’s not enough just poking the silly thing. A couple of years back I rang the bell diligently enough at the Park Avenue co-op of a charming couple named Sandoval, poked the little button until my finger throbbed, and wound up going directly to jail without passing Go. The bell was out of order, the Sandovals were home scoffing toasted English muffins in the breakfast nook, and Bernard G. Rhodenbarr soon found himself in a little room with bars on the windows.

This bell was in order. When my second ring brought no more response than my first, I reached a hand beneath my topcoat-last year’s model, not plaid but olive-and drew a pigskin case from my trouser pocket. There were several keys in the case and several other useful things as well, these last made of the finest German steel. I opened my case, knocked on the door for luck, and set to work.

A funny thing. The better your building, the higher your monthly rental, the more efficient your doorman, why, the easier it’s going to be to crack your apartment. People who live in unattended walkups in Hell’s Kitchen will fasten half a dozen deadbolt locks to their doors and add a Segal police lock for insurance. Tenement dwellers take it for granted that junkies will come to kick their doors in and strong-arm types will rip the cylinders out of their locks, so they make things as secure as they possibly can. But if the building itself is so set up as to intimidate your garden variety snatch-and-grab artist, then most tenants make do with the lock the landlord provides.

In this case the landlord provided a Rabson. Now there’s nothing tacky about a Rabson lock. The Rabson is very good. But then so am I.

I suppose it took me a minute to open the lock. A minute may be long or short, significant or inconsequential. It is long indeed when you are spending it inserting burglar’s tools into a lock of an apartment manifestly not your own, and when you know that during any of its sixty seconds another door down the hallway might open and some Nosey Parker might want to know just who you think you are and just what you think you are doing.
