our catching the disease. One doesn't want to seek trouble. Keep away from the hospital."
"Rubbish!" said Jean briskly. "If Lydia wants to go, there is no reason why she shouldn't. The isolation people are never allowed to come into contact with visitors, so there is really no danger."
"I agree with Mrs. Cole-Mortimer," grumbled Briggerland. "It is very foolish to ask for trouble. You take my advice, my dear, and keep away."
"I had a talk with a gendarme this morning," said Lydia to change the subject. "When he stopped and got off his bicycle I thought he was going to speak about the shooting. I suppose it was reported to the police?"
"Er--yes," said Mr. Briggerland, not looking up from his plate, "of course. Have you been into Monte Carlo?"
Lydia shook her head.
"No, I couldn't sleep, and I was taking a walk along the road when he passed." She said nothing about Mr. Jaggs. "The police at Monaco are very sociable."
Mr. Briggerland sniffed.
"Very," he said.
"Have they any theories?" she asked. In her innocence she was persisting in a subject which was wholly distasteful to Mr. Briggerland. "About the shooting I mean?"
"Yes, they have theories, but my dear, I should advise you not to discuss the matter with the police. The fact is," invented Mr. Briggerland, "I told them that you were unaware of the fact that you had been shot at, and if you discussed it with the police, you would make me look rather foolish."
When Lydia and Mrs. Cole-Mortimer had gone, Jean seized an opportunity which the absence of the maid offered.
"I hope you are beginning to see how perfectly insane your scheme was," she said. "You have to support your act with a whole series of bungling lies. Possibly Marcus, like a fool, has mentioned it in Monte Carlo, and we shall have the detectives out here asking why you have not reported the matter."
"If I were as clever as you----" he growled.
"You're not," said Jean, rolling her serviette. "You're the most un-clever man I know."
Chapter XXIV
Lydia went up to her bedroom to put away her clothes and found the maid making the bed.
"Oh, madame," said the girl, "I forgot to speak to you about a matter--I hope madame will not be angry."
"I'm hardly likely to be angry on a morning like this," said Lydia.
"It is because of this matter," said the girl. She groped in her pocket and brought out a small shining object, and Lydia took it from her hand.
"This matter" was a tiny silver cross, so small that a five-franc piece would have covered it easily. It was brightly polished and apparently had seen service.
"When we took your bed, after the atrocious and mysterious happening," said the maid rapidly, "this was found in the sheets. It was not thought that it could possibly be madame's, because it was so poor, until this morning when it was suggested that it might be a souvenir that madame values."
"You found it in the sheets?" asked Lydia in surprise.
"Yes, madame."
"It doesn't belong to me," said Lydia. "Perhaps it belongs to Madame Cole-Mortimer. I will show it to her."
Mrs. Cole-Mortimer was a devout Catholic and it might easily be some cherished keep-sake of hers.
The girl carried the cross to the window; an "X" had been scrawled by some sharp-pointed instrument at the junction of the bars. There was no other mark to identify the trinket.
She put the cross in her bag, and when she saw Mrs. Cole-Mortimer again she forgot to ask her about it.
The car drove her into Nice alone. Jean did not feel inclined to make the journey and Lydia rather enjoyed the solitude.
The isolation hospital was at the top of the hill and she found some difficulty in obtaining admission at this hour. The arrival of the chief medical officer, however, saved her from making the journey in vain. The report he gave about the child was very satisfactory; the mother was in the isolation ward.
"Can she be seen?"
"Yes, madame," said the urbane Frenchman in charge. "You understand, you will not be able to get near her? It will be rather like interviewing a prisoner, for she will be behind one set of bars and you behind another."
Lydia was taken to a room which was, she imagined, very much like a room in which prisoners interviewed their distressed relations. There were not exactly bars, but two large mesh nets of steel separated the visitor from the patient under observation. After a time a nun brought in the gardener's wife, a tall, gaunt woman, who was a native of Marseilles, and spoke the confusing patois of that city with great rapidity. It was some time before Lydia could accustom her ear to the queer dialect.
Her boy was getting well, she said, but she herself was in terrible trouble. She had no money for the extra food she required. Her husband who was away in Paris when the child had been taken, had not troubled to write to her. It was terrible being in a place amongst other fever cases, and she was certain that her days were numbered....
Lydia pushed a five-hundred franc note through the grating to the nun, to settle her material needs.
"And, oh, madame," wailed the gardener's wife, "my poor little boy has lost the gift of the Reverend Mother of San Surplice! His own cross which has been blessed by his holiness the Pope! It is because I left his cross in his little shirt that he is getting better, but now it is lost and I am sure these thieving doctors have taken it."
"A cross?" said Lydia. "What sort of a cross?"
"It was a silver cross, madame; the value in money was nothing--it was priceless. Little Xavier----"
"Xavier?" repeated Lydia, remembering the "X" on the trinket that had been found in her bed. "Wait a moment, madame." She opened her bag and took out the tiny silver symbol, and at the sight of it the woman burst into a volley of joyful thanks.
"It is the same, the same, madame! It has a small 'X' which the Reverend Mother scratched with her own blessed scissors!"
Lydia pushed the cross through the net and the nun handed it to the woman.
"It is the same, it is the same!" she cried. "Oh, thank you, madame! Now my heart is glad...."
Lydia came out of the hospital and walked through the gardens by the doctor's side. But she was not listening to what he was saying--her mind was fully occupied with the mystery of the silver cross.
It was little Xavier's ... it had been tucked inside his bed when he lay, as his mother thought, dying ... and it had been found in her bed! Then little Xavier had been in her bed! Her foot was on the step of the car when it came to her--the meaning of that drenched couch and the empty bottle of peroxide. Xavier had been put there,
