prig of a man in butlerâs livery, had been conventional enough. âIn fact, Charley, if you could give me a glimpse of the various Pottses before dinner in their native habitat I should be ever so much obliged.â
âI canât imagine anyone wanting to meet them except through necessity, but I suppose thatâs what distinguishes you from all other men. This way, Professor. Letâs see which Potts we can scare up first.â
At the top of the staircase stood a landing, most specious and hushed, and long halls leading away. Charley turned a corner, and there yawned the entrance to what looked like a narrow tower. âThatâs just what it is,â nodded Charley. âUp wiâ ye!â
They mounted a steep coil of steps. âI didnât notice this campanile from outside. Why, Charley?â
âItâs a peculiarity of construction. The tower faces an inner court and canât be seen from the street.â
âAnd it leads where?â
âTo Louellaâs lair ⦠Here.â
Charley knocked on a door with a grille in it backed by thick glass. A female face goggled through the glass, eyed Mr. Paxton with suspicion, withdrew. Bolts clanked. Ellery felt a sensible prickling along his spine when the door screeched open.
Louella Potts was not merely thinâa more desiccated figure he had not seen outside the Morgue. And she was utterly uncared-for. Her gray-dappled coarse brown hair was knotted at her scrawny neck and was all wisps and ends over her eyes. The eyes, like the eyes of the mother, fascinated him. But these, while brilliant, were full of pain, and between them the flesh was set in a permanent puzzle of inquiry. Louella Potts wore a laboratory smock which fitted her like a shroud, and shapeless huaraches. No stockings, Ellery noted. He also noted varicose veins, and looked away.
The laboratory was circularâa clutter of tables, retorts, goose-necked flasks, Bunsen burners, messy bottle-filled shelves, taps, benches, electrical apparatus. What it was all for Ellery had no idea; but it looked impressive in a cinematic sort of way.
âQueen?â she shrilled in a voice as tall and thin as herself. âQueen.â The frown deepened until it resembled an old knife wound. âYou arenât connected with the Mulqueen General Laboratories, are you?â
âNo, Miss Potts,â said Ellery tensely.
âYou see, theyâve been after my invention. Just thieves, of course. I have to be carefulâI do hope youâll understand. Will you excuse me now? I have a tremendously important experiment to conclude before dinner.â
âReminds you of the Mad Scientist in The Crimson Clue, doesnât she?â Charley shuddered as they made their way down the tower stairs.
âWhatâs she inventing?â
âA new plastic to be used in the manufacture of shoes,â replied Charley Paxton dryly. âAccording to Louella, this material sheâs dreaming up will last forever. People will be able to buy one pair of shoes and use them for life.â
âBut that would ruin the Potts Shoe Company!â
âOf course. But what else would you expect a Potts to spend her time inventing? Come onâIâll introduce you to Horatio.â
They were in the foyer again. Charley led the way towards a panel of tall French doors set in a rear wall.
âHouse is built in a U,â he explained. âWithin the U are a patio and an inner court, and more grounds, and Horatioâs dream house and so on. Iâve had architects here whoâve gone screaming into the night ⦠Ooops. There are Steve and the Major.â
âSheilaâs father and the companion of his Polynesian youth?â
They were two crimson-cheeked elderly men, seemingly quite sane. They were seated in a small library directly off the rear of the foyer, a checkerboard between them. The rear wall of the library was a continuation of the
