"As you wish," said the detective.

But he wondered who this unknown woman could be. When she said he would not remember her name, did she mean to imply that he had once been acquainted with it? If so, she was right in thinking that he did not recognize her now; but, if she did not choose to raise the thick c.r.a.pe veil that hid her face, she could hardly expect him to do so.

He wondered whether she kept her veil lowered with the intention of preventing his recognizing her, or whether in truth she were anxious not to expose grief-swollen features to an unsympathetic gaze.

Her voice, which was low and sorrowful, though at the same time curiously resonant, seemed to suggest that she was in great trouble. She spoke, he fancied, with a trace of foreign accent.

For the rest, all that he could tell for certain about her was that she was short and slender, with small feet, and hands, from which she was now engaged in deliberately withdrawing a pair of black suede gloves.

He watched her in silence. He always preferred to let people tell their stories at their own pace and in their own way, unless they were of those who plainly needed to be helped out with questions.

And about this woman there was no suspicion of embarra.s.sment; her whole demeanour spoke of calmness and self-possession.

"I believe," she said at last, "that you are a private detective. I come to ask for your help in a matter of some difficulty. Some papers of the utmost importance, not only to me but to others, are in the possession of a person who intends to profit by the information contained in them to do myself and my friends an irreparable injury. You can imagine how anxious we are to obtain them from him."

"Do I understand that this person threatens you with blackmail?" asked Gimblet.

The lady hesitated.

"Something of the kind," she replied after a moment's pause.

"And you have so far given in to his demands?"

"Yes," admitted the visitor. "Up till now we have been obliged to submit."

"Has he proposed any terms on which he will be willing to return you the papers?" asked the detective.

"No," she replied. "I do not think any terms are possible."

"How did this person obtain possession of the papers?" Gimblet asked after a moment. "Did he steal them from you?"

"No."

"From your friends?"

She hesitated.

"No-not exactly."

"From whom, then?" asked Gimblet in surprise. "I suppose they were yours in the first place?"

"He has always had them," she said reluctantly; "but they must not remain his."

"Do you mean they are his own?" exclaimed Gimblet. "In that case it is you who propose to steal them!"

"No," replied the strange lady calmly. "I want you to do that."

"I'm sorry," said Gimblet; "that is not in my line of business. I'm afraid you made a mistake in coming to me. I cannot undertake your commission."

"Money is no object; we shall ask you to name your own price," urged his visitor.

But the detective shook his head.

"It is a matter of life and death," she said, and her voice betrayed an agitation which could not have been inferred from her motionless shrouded figure. "If you refuse to help me, not one life, but many, will be endangered."

"If you can offer me convincing proof of that," said Gimblet, "I might feel it my duty to help you. I don't say I should, but I might. In any case I can do nothing unless you are perfectly open and frank with me. Expect no a.s.sistance from me unless you tell me everything, and then only if I think it right to give it."

For the first time she showed some signs of confusion. The hand upon her lap moved restlessly and she turned her head slowly towards the window as if in search of suitable words. But she did not speak or rise, though she gradually fidgeted round in her chair till she faced the writing-table; and so sat, with her head leaning on her hand, in silent consideration.

It was clear she did not like Gimblet's terms; and after a few minutes had pa.s.sed in a silence as awkward as it was suggestive he pushed back his chair and stood up. He hoped she would take the hint and bring an unprofitable and embarra.s.sing interview to an end.

But she did not appear to notice him, and still sat lost in her own thoughts.

Suddenly the door opened and Higgs appeared.

Gimblet looked at him with questioning disapproval.

It was an inflexible rule of his that when engaged with a client he was not to be disturbed.

Higgs, well acquainted with this rule, hovered doubtfully in the doorway, displaying on the salver he carried the blue, unaddressed envelope Lord Ashiel had told him to deliver at once.

"It's a note, sir," he murmured hesitatingly. "The gentleman who was with you a little while ago came back with it. He asked me to be sure and bring it in at once."

He avoided Gimblet's reproachful eye and stammered uneasily:

"Put it down on that table and go," said the detective. He indicated a little table by the door, and Higgs hastily placed the letter on it and fled, with the uncomfortable sensation of having been sternly reproved.

As a matter of fact Gimblet would have shown more indignation if he had not at heart felt rather glad of the interruption. His visitor had decidedly outstayed her welcome; and, though she stirred his curiosity sufficiently to make him wish he could induce her to raise her veil and let him see what manner of woman it was who had the effrontery to come and make him such unblushing proposals, he far more urgently desired to see the last of her. She was wasting his time and annoying him into the bargain.

As the door shut behind the servant he made a step towards her.

"If, madam, there is nothing else you wish to consult me about," he began, taking out his watch with some ostentation-"I am a busy man-"

The lady gave a little laugh, low and musical.

"I will not detain you longer," she said, also rising from her chair. "I am afraid I have cut into your afternoon, but you will still have time for a game if you hurry."

She laughed again, and moved over to the writing-table, where, among a litter of papers and writing materials, a couple of golf b.a.l.l.s were acting as letter weights. A putter lay on the chair in front of the desk, and she took it up and swung it to and fro.

"A nice club," she remarked. "Where do you play, as a rule? There are so many good links near London; so convenient. Well, I mustn't keep you." She laid down the putter and fingered the b.a.l.l.s for a moment. "Where have I put my gloves?" she said then, looking around to collect her belongings.

Gimblet was slightly put out at her inference that his plea of business was merely an excuse to dismiss her in order that he might go off and play golf. Heaven knew it was no affair of hers whether he played golf that day or not! But as a matter of fact he had no intention of leaving the flat that afternoon, and had merely been practising a shot or two on the carpet after lunch before Lord Ashiel's arrival. Still it was true that he had made business a pretext for getting rid of her, and this made the injustice of the widow's further inference ruffle him more than it might have if she had been entirely in the wrong. He was the most courteous of men, and that anyone should suspect him of unnecessary rudeness distressed him.

He made no reply, however, in spite of the temptation to defend himself; but stooped to pick up a diminutive black suede glove which his visitor had dropped when she took up the putter.

She thanked him and put it on, depositing, while she did so, her other glove, her handkerchief, sunshade and a small brown-paper parcel upon the writing-table at her side.

Gimblet did not appreciate seeing these articles heaped upon his correspondence. Without any comment he removed them, and stood holding them silently till she should be ready.
