So much for the Krugerrands. So much, too, for a shoulder-height set of glassed-in shelves full of Boehm birds and Art Nouveau vases and glass paperweights. I spotted a Lalique ashtray just like the one on my grandmother’s coffee table, and a positive gem of a Daum Nancy vase, and Baccarat and Millefiori weights galore, and-

It was starting to get to me. I couldn’t look anywhere without seeing ten things I wanted to steal. Every flat surface in that study held bronzes, all of them impressive. Besides the usual bulls and lions and horses, I noticed one of a camel kneeling alongside a Legionnaire. The latter wore a kepi on his head and a pained expression on his face, as if he were sick of jokes about Legionnaire’s Disease.

A couple of stamp albums. One general worldwide collection that didn’t look to be worth much, but the other was a Scott Specialty Album for the Benelux countries, and a quick thumbing didn’t reveal too many blank spaces.

And a coin collection. Lord above, a coin collection! No albums, just a dozen black cardboard boxes two inches square and ten inches long. Each was crammed to capacity with two-by-two coin envelopes. I didn’t have time to check them but I couldn’t resist. I opened one box at random and found it was filled with Barber quarters and halves, all Proofs or Uncirculated specimens. Another box contained superb Large Cents catalogued by Sheldon numbers.

How could I possibly leave them?

I left them. I didn’t take a thing.

I was in one of the guest bedrooms on the second floor, playing my penlight over the walls and admiring a very nice pencil-signed Rouault lithograph, when I heard a car in the driveway. I checked my watch. It was 11:23. I listened as the automatic garage door swung upward, listened as the car’s engine cut out. As the garage door swung down again I quit listening and walked the length of the hall to the staircase leading to the third floor. I was up those stairs and crouching on the third-floor landing by the time Jesse Arkwright’s key hit the slot at the side of the house. First he turned off the burglar alarm, then he opened the door, and I fancied I could hear him refastening half a dozen locks after he and Elfrida had made their entrance.

Muffled conversation, barely audible two floors below me. I moved a rubber-gloved forefinger and wiped perspiration from my forehead. I’d planned on this, of course. I’d even checked the attic stairs earlier to make sure there were no squeakers in the lot.

All the same, I didn’t like it. Burglary’s a tightly wired proposition at best, but I generally get to do my work in precious solitude. If householders come home while I’m on the job, my usual impulse is to depart abruptly.

This time I had to linger.

Two floors below, a teakettle whistled briefly, then sighed as someone removed it from the flame. For an instant I’d mistaken its cry for a police siren. Nerves, I thought, taking deep breaths, beseeching the patron saint of burglars for a dose of serenity.

Maybe I’d been right when I talked to Kirschmann. Maybe I was getting too old for this. Maybe I didn’t have the requisite sang-froid. Maybe-

Crouching was uncomfortable. I got stiffly to my feet. The attic was finished off, its central hallway covered with a length of faded maroon carpeting. I walked clear to the front of the house, where a brass floorlamp equipped with a timer sent out forty watts’ worth of light through a curtained window. A maid’s room, it looked to be, although the household no longer employed live-in servants.

A day bed stretched along one wall. I lay down on top of it pulled a green and gold afghan coverlet over myself, and closed my eyes.

I couldn’t really hear much from where I was. At one point I thought I heard footsteps on the stairs, and then a few moments later I fancied that I could hear the clatter of balls on the pool table in the library. This was probably a case of my imagination filling in the blanks. After an evening at the theater, the Arkwright routine was supposed to be quite predictable. Home around eleven-thirty, a spot of coffee and something sweet in the breakfast nook, and then Elfrida would pop upstairs with a book of crosswords while Jesse ran a rack or two at the pool table, nipped at one of the crystal decanters, read a few pages of one of his leather-bound classics, and then hied his own bulk up the stairs and joined his wife in their chamber.

Would he take a final tour of the downstairs, making sure all the doors were locked? Would he happen to check the sliding bolt on the kitchen door, and would he happen to notice that some clever chap had sawn through it? Was he, even as I thought these grim thoughts, lifting a receiver to summon the local constabulary?

I could have been at the ballet, watching a Russian imitate a gazelle. I could have gone home with Carolyn and eaten Flemish stew and drunk Dutch beer. Or I could have been home in my own little bed.

I stayed where I was and I waited.

At one-thirty I got to my feet. I hadn’t heard a sound within the house for an entire half-hour. I padded silently to the stairs, crossing right over the master bedroom where I hoped my hosts were sleeping soundly. I went down the stairs, treading ever so gingerly on my crepe soles, and I crossed the second-floor hallway and went on down the other stairs to the ground floor. It was no great feat to remember to avoid the fourth step from the top; I’d obsessed on that very subject for the past twenty minutes.

The lights were out once again on the ground floor, except for the indomitable dragonfly lamp in the living room. I didn’t have to use my penlight to find my way to the library, but once I was in that room I played its beam here and there.

Arkwright had paid the room his nightly visit. He’d left a pool cue on top of the table, along with the cue ball and one or two of its fellows. A small brandy snifter stood on a leather-topped table beside one of the big chain. It was empty, but a quick sniff revealed it had recently held cognac-a very good cognac at that, judging from the bouquet.

There was a book next to the snifter, Sheridan’s Plays, bound in red leather. Bedtime reading.

I went to the bookshelves. Had Arkwright inspected the little green clothbound volume as part of his nightly ritual? I couldn’t tell, as it was right where I’d found it earlier in the evening. But it was his treasure. He’d probably had a look at it.

I took it from the shelf and just managed to fit it into my jacket pocket. Then I nudged the surrounding volumes so as to fill up the space where it had been.

And left the library.

He had turned off the alarm to enter the house, then reset it once he and Elfrida were inside. All the while, of course, the alarm system continued to guard all of the house but the kitchen door. I now left through that very portal, closing it after me and relocking its three locks by picking them in reverse. I had to leave the chain bolt dangling and I couldn’t do anything about the bolt I’d hacksawed earlier. Nobody’s perfect.

I was very damned close to perfection, though, in the way I restored the alarm system, rewiring it to render the kitchen door once more unbreachable. Every impulse urged me to quit Arkwright’s property while I had the chance, but I spent a few extra minutes, and only an imperceptible scrap of electrical tape hinted that the wires had ever been tampered with.

Professionalism? I call it the relentless pursuit of excellence.

I had almost reached the end of Copperwood Crescent when the police car turned the corner. I managed to furnish a smile and a perfunctory nod without breaking stride. They went along their merry way, and why not? They’d seen only a well-dressed and self-possessed gentleman who looked as though he belonged.

They hadn’t seen any palmless rubber gloves. Those wound up tucked in a pocket before I left the Arkwright driveway.
