The countenance of the sallow-faced man recurred to me. It was an alarming possibility that Burke’s speculation raised. Were we really not involved in a pure murder case, but in the intricacies of the machinations of some unknown power?
Burke looked at his watch, then again at Kennedy. ‘Really, I think you ought to go back to town,’ he reiterated, ‘and take the case up there.’
‘And leave these people all here to do as they please, cover up what they will?’ objected Hastings, who had tried to prevent just that sort of thing by bringing Kennedy out post-haste.
‘My men are perfectly competent to watch anything that goes on at Westport,’ returned Burke. ‘I have them posted all about and I’m digging up some good stuff. Already I know just what happened the night before the conference. That cabaret dancer, Paquita, motored out here and arrived about the time the Sybarite cast anchor. She met Shelby Maddox at the Casino and they had a gay supper party. But it ended early. She knew that Marshall Maddox was coming the next day. I know he had known her in the city. As to Shelby we don’t know yet. The meeting may have been chance or it may have been prearranged.’
I recalled not only the little incident we had just seen, but the glance of jealousy Paquita had given Shelby when she saw him with Winifred. What did it mean? Had Shelby Maddox been using Paquita against his brother, and now was he trying to cast her off? Or was Burke’s theory correct? Was she a member of a clever band of super-criminals, playing one brother against the other for some ulterior end? Was the jealousy feigned or was it real, after all?
‘What I am endeavouring to do now,’ went on Burke, ‘is to trace the doings of Paquita the night of the murder. I cannot find out whether she came out at the invitation of Marshall Maddox or not. Perhaps it was Shelby. I don’t know. If it was Marshall, what about his former wife? Did he suppose that she would not be here? Or didn’t he care?’
‘Perhaps—blackmail,’ suggested Hastings, who, as a lawyer, had had more or less to do with such attempts.
Burke shook his head. ‘It might have been, of course, but in that case don’t you think you, as Maddox’s lawyer, would have heard something of it? You have not—have you? You don’t know anything about her?’
Burke regarded the lawyer keenly, as though he might be concealing something. But Hastings merely shook his head.
‘Mr Maddox did not confide his weaknesses to me,’ Hastings remarked coldly.
‘If we are going back to the city,’ returned Burke, cheerfully changing the subject, to the evident surprise of Hastings, ‘I must find my operative, Riley, and let him know what to do while we are gone.’
‘Look,’ muttered Kennedy under his breath to us and nodding down the lobby.
Shelby Maddox had sought and found Winifred, and was chatting as animatedly as if there had been no Paquita in the world less than five minutes before.
As we watched, Hastings remarked: ‘It was only the day before the murder that Shelby first met Winifred Walcott. I believe he had never seen his brother-in-law’s sister before. She had been away in the West ever since Frances Maddox married Walcott. Winifred seems to have made a quick conquest.’
Remembering what had happened before, I took a quick look about to see whether anyone else was as interested as ourselves. Seeing no one, Kennedy and I strolled down the corridor quietly.
We had not gone far before we stopped simultaneously. Nestled in the protecting wings of a big wicker chair was Paquita, and as we watched her she never took her eyes from the couple ahead.
What did this constant espionage of Shelby mean? For one thing, we must place this little adventuress in the drama of the Maddox house of hate. We moved back a bit where we could see them all.
A light footfall beside us caused us to turn suddenly. It was Mito, padding along on some errand to his master. As he passed I saw that his beady eyes had noted that we were watching Shelby. There was no use to retreat now. We had been observed. Mito passed, bestowing a quick sidewise glance on Paquita as he did so. A moment later he approached Shelby deferentially and stood waiting a few feet away.
Shelby looked up and saw his valet, bowed an excuse to Winifred, and strode over to where Mito was standing. The conversation was brief. What it was about we had no means of determining, but of one thing we were certain. Mito had not neglected a hasty word to his master that he was watched. For, an instant later when Mito had been dismissed, Shelby returned to Winifred and they walked deliberately out of the hotel across a wide stretch of open lawn in the direction of the tennis-courts. To follow him was a confession that we were watching. Evidently, too, that had been Shelby’s purpose, for as he chatted he turned half-way, now and then, to see if they were observed. Again Mito padded by and I fancied I caught a subtle smile on his saturnine face. If we were watching, we were ourselves no less watched.
There was nothing to be gained in this blind game of hide-and-seek, and Kennedy was evidently not yet prepared to come out into the open. Paquita, too, seemed to relinquish the espionage for the moment, for she rose and walked slowly toward the Casino, where she was quickly joined by some of her more ardent admirers.
I glanced at Kennedy.
‘I think we had better go back to Burke and Hastings,’ he decided. ‘Burke is right. His men can do almost as much here as we could at present. Besides, if we go away the mice may play. They will think we have been caught napping. That telautomaton robbery is surely our next big point of attack. Here it is first of all the mystery of Marshall Maddox’s death, and I cannot do anything more until the coroner sends me, as he has promised, the materials from the autopsy. Even then I shall need to be in my laboratory if I am to discover anything.’
‘Your sallow-faced friend seemed quite interested in you,’ commented Burke as we rejoined him.
‘How’s that?’ inquired Kennedy.
‘From here I could see him, following every move you made,’ explained the Secret Service man.
Kennedy bit his lip. Not only had Mito seen us and conveyed a warning to Shelby, but the dark-skinned man of mystery had been watching us all. Evidently the situation was considerably mixed. Perhaps if we went away it would really clear itself up and we might place these people more accurately with reference to one another.
Burke looked at his watch hurriedly. ‘There’s a train that leaves in twenty minutes,’ he announced. ‘We can make the station in a car in fifteen.’
Kennedy and I followed him to the door, while Hastings trailed along reluctantly, not yet assured that it would be safe to leave Westport so soon.
At the door a man stepped up deferentially to Burke, with a glance of inquiry at us.
‘It’s all right, Riley,’ reassured Burke. ‘You can talk before them. One of my best operatives, Riley, gentlemen. I shall leave this end in your charge, Val.’
‘All right, sir,’ returned the Secret Service operative. ‘I was just going to say, about that dark fellow we saw gum-shoeing it about. We’re watching him. We picked him up on the beach during the bathing hour. Do you know who he is? He’s the private detective whom Mrs Maddox had watching
