doctor lessing re-entered the room with a letter in his hand.

"the last address i can find," he said, "is 35, de vere terrace, streatham. that is sixteen years old, but as it tells me that she had only just moved in, you might find her still there."

monsieur dupont made a note of the address.

"there remains only one question," he said, replacing his pocket-book. "can you tell me the name of the child?"

the doctor shook his head.

"i'm afraid i can't. the child was christened in the church here, but i was away at the time, and when i returned miss masters had gone to london."

"it is very important," said monsieur dupont. [pg 188]"perhaps i can discover it at the church?"

"you will not find any one to tell you at this time," the doctor replied. "but, if you will leave me your address, i will send over to the parsonage this evening and ask mr. wickham to turn it up in the register, and let you know."

monsieur dupont delivered himself of profuse thanks. five minutes later he had taken leave of the old doctor, and was returning to the station under the guidance of the sunburnt youth, who was obviously relieved when the expedition terminated.

he slept peacefully until the train reached paddington.

it was five o'clock when he returned to the savoy. the girl, jenny west, was waiting for him. she was as white as death.

"they have charged him," she sobbed. "he is remanded for a week."

he laid a hand gently on her shoulder.

"do not be afraid," he said. "he will be saved. i have given my word—the word of dupont—that he will be saved."

[pg 189]he sat down at his writing table, and wrote rapidly for several minutes. he covered four or five sheets of paper, and placed them in an envelope.

"here, mademoiselle," he said, rising, "are your instructions for to-morrow morning. do not read them until you are alone. a car will be waiting for you here at ten o'clock in the morning. in the afternoon you will be at liberty to visit monsieur layton. i shall expect to see you here at one o'clock."

he bowed her out of the room. half an hour later, he was on his way to streatham.

a grim expression settled on his face as the journey proceeded, yet it was not altogether unmixed with pity. he was a man of ready sympathy. the doctor's story had evidently moved him to view his task with a new compassion.

as his car turned into de vere terrace, he became alert, and scrutinized the houses closely. they were small semi-detached villas. he alighted in front of number 35, passed up [pg 190]the carefully kept front garden, and knocked at the door.

there was no response. he knocked again, several times, but the silence of the house remained undisturbed. he left the door, and glanced in at the front windows, but the room was so dark that he could discern nothing. he walked round to the back. through the uncurtained kitchen windows he saw a fire in the range. it had almost burnt itself out. there were cooking utensils on the table. some pastry was rolled out on a board. apparently the household operations had been somewhat rudely interrupted, and very hastily abandoned. the back door and windows were securely fastened. returning to the front, he carefully closed the gate, and knocked at the door of the adjoining house.

the name of the house was "sans souci," and the door was opened by a lady in rich purple, with a string of pearls.

monsieur dupont swept off his hat.

"madame, i make a thousand apologies! can you tell me when i shall find miss masters at home."

[pg 191]his extreme bulk and the fact that he was not an englishman seemed to cause the lady considerable amusement.

"i'm sure i don't know," she said engagingly. "i think she's gone away."

"away?" monsieur dupont echoed.

"she left in a great hurry two hours ago," the lady informed him. "in a motor."

monsieur dupont appeared somewhat staggered.

"two hours ago...." he muttered.

"i heard a noise going on in the house," continued the lady, "as if she was packing quickly. she went off with a couple of boxes, and seemed very impatient."

"it is most unfortunate," said monsieur dupont mildly. "i have come all the way from the strand to see her."

the lady laughed freely.

"i'm very sorry," she said good-naturedly. "won't you come in and rest a bit?"

"madame," he said, "you are very good, but i must return to the strand. would you allow me to ask you some questions, without finding me impertinent?"

[pg 192]"what are they?" she asked.

"will you tell me if any particular person was in the habit of visiting miss masters?"

the lady stiffened slightly.

"are you a friend of miss masters?" she inquired, shortly.

"i am not," monsieur dupont admitted frankly. "i have never seen her. it is a few hours ago that i heard her name for the first time."

"i really cannot answer any questions to a stranger," said the lady stiffly. "i don't know you."

monsieur dupont bowed.

"if you did, madame," he said, "i should be the proudest of men. do me the favor to read this letter."

he produced the letter from the french embassy, and handed it to her. she read it, and was duly impressed.

"of course i'll do anything for the french embassy," she said, returning the letter with dignity. "miss masters wasn't what you might call a friend of mine. i used to speak to her because she lived in the next house, but [pg 193]it didn't go beyond that. she kept very much to herself. i don't want to say anything at all unkind, but very few ladies in our set knew her. of course it wasn't her fault, but she was not exactly classy. and when one lives in a neighborhood like this, it's class that tells."

monsieur dupont bowed again.

"obviously, madame," he said.

"the only person that used to visit her," continued the gratified lady, "was a man who often used to arrive in the evening and stay the night. we understood she was an old nurse of his, or something of the kind, and that he more or less provided for her."

"and this man, madame—what was he like?"

"he was rather tall," she said, "and had a dark moustache. he was always well dressed, and looked quite a gentleman."

"you heard his name?"

"no—we never heard his name. i did tell my house-parlor-maid to try to find out once, but she couldn't. miss masters actually accused me of prying."

"mon dieu," said monsieur dupont.

[pg 194]"we had a bit of a row," said the lady candidly.

"does she live alone, madame?"

"yes, quite alone. she does everything for herself."

"my last question," said monsieur dupont, "may seem remarkable. it is this. have strange things appeared to be happening in the house during the visits of the tall gentleman with the dark moustache?"

she started, looking at him curiously.

"strange things?" she repeated slowly.

"perhaps—violent things."

"well, that's queer," she exclaimed. "as a matter of fact, we once heard the most extraordinary noises going on when he was there. my husband thought of sending in to ask if anything was the matter."

"what kind of noises, madame?"

"like as it might be heavy things being thrown about and smashed," said the lady elegantly.

monsieur dupont swept off his hat again.

"thank you, madame," he said—and went back to his car.
