There was a brief silence. The infant’s vest revolved. The colour really was extremely pretty. Miss Silver appeared to be concentrating her attention upon the clicking needles. Presently, whilst continuing to knit, she raised her eyes and said briskly,
“Was there a fire in the hall?”
“Yes, I believe so.”
“Then how much light did it give? As I passed just now I observed that there was a good wood fire. Such a fire would throw out a considerable amount of light. It would affect the question of whether Mr. Tote could have made his way across the hall without being observed and-”
Frank Abbott interrupted.
“Yes, I know-you think of everything, don’t you? I ought to have told you that the fire had been dowsed.”
“By whom?”
“By Masterman, under Carroll’s orders. Carroll couldn’t do with the firelight for his charade. He wanted the hall to be dark, with the single lamp on the mantelpiece arranged to be as much like a spotlight as possible. They put a cone of brown paper on it and tilted it so that the light fell in a pool just where it caught his people one by one as they came down off the bottom step and turned at the newel. Leigh says it was very effective. They came down the stairs and passed through the light and out of it into the dark back of the hall. Masterman was in charge of the lighting. Carroll told him to dowse the fire. He was also first in the procession, and when he had done his part he worked round the edge of the hall and came back to the hearth, ready to turn on the lights when the show was over. I say that Tote could have crossed the hall without being noticed, because nobody noticed Masterman work his way back from the service door to the hearth. Of course they were all watching the charade then, but I say Tote could have done it. Everyone would have been moving, and no one would have been thinking about him.”
Miss Silver continued to knit. She said,
“Quite so. There is now a very important point which I wish to raise. Mr. Porlock’s back was marked with luminous paint. How large was this patch?”
“About three inches by four. It was an irregular patch, not a circle. There is no doubt at all about its purpose.”
“No,” said Miss Silver. “Very shocking indeed. But the luminous paint must have been conveyed in some manner which would prevent its spilling and marking not only the victim but the murderer. You yourself suggested a handkerchief. I am inclined to agree. Has any such handkerchief been found?”
“No.”
“If the fire was dowsed, the handkerchief could not have been burned. Did anyone leave the hall before the local Inspector arrived?”
“No. Leigh kept everyone there. He’s an able chap-he wouldn’t let anyone leave the hall. But I’m afraid that when Hughes arrived his ideas of a search were a bit perfunctory. He put the women in a room by themselves whilst he sent for a female searcher, and he had the men searched for bloodstains and paint-marks. There were no bloodstains, either on the men or on the women-there wasn’t any external bleeding. Carroll had smears of luminous paint, and so had Moira Lane and Masterman. It just proves nothing at all. Carroll was smothered with the stuff in his part as the devil, and the charade ended with his embracing Miss Lane. Carroll threw down his luminous mask upon the hall table, and Miss Lane threw her things there too. She was wearing a red velvet dress under her robe, and there was a mark on her left sleeve-rather a wet one. Masterman had a smear on his right cuff. He could have got it stabbing Gregory Porlock, but apparently he didn’t. Moira Lane says he pointed out the mark on her sleeve. She says he brushed up against her, and then exclaimed and said, ‘You’re all over paint. I’ve got some of it on my cuff. Hadn’t you better wipe it off?’ That was before Hughes arrived.”
“My dear Frank!”
“Yes-I know. It’s just what he might have done if he had noticed a smear which would have to be accounted for. On the other hand, he did brush up against her, and she had got a large wet patch on her sleeve. It wouldn’t be any good putting that smear on his cuff to a jury-now, would it?”
“I suppose not-unless there was other evidence in support. Was there anyone else who was marked with the paint?”
“No, there wasn’t. I think Hughes was quite thorough about that. What hadn’t occurred to him was the question as to how the paint had been carried. I think he was all out for Carroll as the murderer, and he took it for granted that the luminous mark on Porlock’s back had been made by a paint-smeared hand. Carroll’s hands were all over paint, and he had gone upstairs to wash them. Nice simple line of explanation-perfectly satisfactory to Hughes, so he never looked below what you might call the surface of the men’s handkerchiefs. I don’t think the paint could have been hidden if it had been on one of those flimsy squares of muslin that women drop about all over the place-it would have come through.”
Miss Silver coughed gently.
“My dear boy, not muslin-cambric, or linen.”
An almost colourless eyebrow jerked.
“Call them anything you like-paint would show through. But a man’s handkerchief could be carefully folded up to hide a paint-stain. Hughes just looked blank when I asked him if he’d had all the handkerchiefs spread out. He hadn’t. You expect a man to have a handkerchief-you take it for granted. At least you don’t, but Hughes did. Which gives the murderer the best part of twenty-four hours to get rid of the evidence. By the time I’d thought about a handkerchief and put Hughes on to going through the house with a toothcomb there naturally wasn’t anything left for him to find.”
Miss Silver put away her knitting and got up.
“I should like to go into the hall, but before we do so, will you tell me what results have been obtained in the way of fingerprints?”
“I think I told you about the four sets of switches. The one at the top of the stairs had been wiped clean. The one by the service door was just a mess. The one by the hearth had Masterman’s prints, and the one by the hall door Justin Leigh’s-both quite innocently accounted for. The dagger had been wiped clean-there were no prints there-” He stopped beneath a searching gaze.
“Were no other prints found?”
The eyebrow jerked again.
“What other prints were there to take? Most of these people were staying in the house. The others had been dining, moving about in the hall. Their prints would be all over the place, and they wouldn’t prove a thing.”
Miss Silver coughed, picked up Justin Leigh’s plan, and led the way into the hall.
It was empty. The electric candles shed a soft light upon the stone flags and the two long Persian runners which crossed them. But Miss Silver was not looking at the floor. She walked over to the hearth and stood there, her eyes lifted to the trophy of arms above the stone mantelshelf. Hanging there on the broad chimney-breast, it had the air of some military decoration pinned to a rough grey coat, for the chimney-breast like the ledge was of stone, breaking the panelled wall. There were old flintlocks, four cumbersome pistols, and a ring of daggers. The bottom dagger was missing. Miss Silver stood looking at the place where it had been.
After a little while she turned round and looked in the direction of the stairs. Then she turned her head, glanced towards the switches on the left-hand side of the hearth, and back again at the staircase. At the sound of approaching voices she went back into the study. When she had seated herself and taken up her knitting again she enquired,
