Over all this placid scene of land and water was a sky such as Doré loved – a great heavy mass of rain-clouds heaped one on top of the other, as the rocks the Titans piled to reach Olympus. Then a break in the woof, and a bit of dark blue sky could be seen glittering with stars, in the midst of which sailed the serene moon, shedding down her light on the cloudland beneath, giving to it all, one silver lining.
Somewhat to the annoyance of Mr. Gorby, who had no eye for the picturesque, Brian gazed at the sky for several minutes, admiring the wonderful beauty of its broken masses of light and shade. At length he lit a cigarette and walked down the steps on to the pier.
"Oh, suicide, is it?" muttered Mr. Gorby. "Not if I can help it." And he lit his pipe and followed him.
He found Brian leaning over the parapet at the end of the pier, looking at the glittering waters beneath, which kept rising and falling in a dreamy rhythm, that soothed and charmed the ear. "Poor girl! poor girl!" the detective heard him mutter as he came up. "If she only knew all! If she – "
At this moment he heard the approaching step, and turned round sharply. The detective saw that his face was ghastly pale in the moonlight, and his brows wrinkled in anger.
"What the devil do you want?" he burst out, as Gorby paused.
"What do you mean by following me all over the place?"
"Saw me, watching the house," said Gorby to himself. "I'm not following you, sir," he said aloud. "I suppose the pier ain't private property. I only came down here for a breath of fresh air."
Fitzgerald did not answer, but turned sharply on his heel, and walked quickly up the pier, leaving Gorby staring after him.
"He's getting frightened," soliloquised the detective to himself, as he strolled easily along, keeping the black figure in front well in view. "I'll have to keep a sharp eye on him or he'll be clearing out of Victoria."
Brian walked rapidly up to the St. Kilda station, for on looking at his watch he found that he would just have time to catch the last train. He arrived a few minutes before it started, so, getting into the smoking carriage at the near end of the platform, he lit a cigarette, and, leaning back in his seat, watched the late comers hurrying into the station. Just as the last bell rang he saw a man rush along, to catch the train. It was the same man who had been watching him the whole evening, and Brian felt confident that he was being followed. He comforted himself, however, with the thought that this pertinacious follower might lose the train, and, being in the last carriage himself, he kept a look out along the platform, expecting to see his friend of the Esplanade standing disappointed on it. There was no appearance of him, so Brian, sinking back into his seat, lamented his ill-luck in not shaking off this man who kept him under such strict surveillance.
"Confound him!" he muttered softly. "I expect he will follow me to East Melbourne, and find out where I live, but he shan't if I can help it."
There was no one but himself in the carriage, and he felt relieved at this because he was in no humour to hear chatter.
"Murdered in a cab," he said, lighting a fresh cigarette, and blowing a cloud of smoke. "A romance in real life, which beats Miss Braddon hollow. There is one thing certain, he won't come between Madge and me again. Poor Madge!" with an impatient sigh. "If she only knew all, there would not be much chance of our marriage; but she can never find out, and I don't suppose anyone else will."
Here a thought suddenly struck him, and rising out of his seat, he walked to the other end of the carriage, and threw himself on the cushions, as if desirous to escape from himself.
"What grounds can that man have for suspecting me?" he said aloud. "No one knows I was with Whyte on that night, and the police can't possibly bring forward any evidence to show that I was. Pshaw!" he went on, impatiently buttoning up his coat. "I am like a child, afraid of my shadow – the fellow on the pier is only some one out for a breath of fresh air, as he said himself – I am quite safe."
At the same time, he felt by no means easy in his mind, and as he stepped out on to the platform at the Melbourne station he looked round apprehensively, as if he half expected to feel the detective's hand upon his shoulder. But he saw no one at all like the man he had met on the St. Kilda pier, and with a sigh of relief he left the station. Mr. Gorby, however, was not far away. He was following at a safe distance. Brian walked slowly along Flinders Street apparently deep in thought. He turned up Russell Street and did not stop until he found himself close to the Burke and Wills' monument – the exact spot where the cab had stopped on the night of Whyte's murder.
"Ah!" said the detective to himself, as he stood in the shadow on the opposite side of the street. "You're going to have a look at it, are you? – I wouldn't, if I were you – it's dangerous."
Fitzgerald stood for a few minutes at the corner, and then walked up Collins Street. When he got to the cab-stand, opposite the Melbourne Club, still suspecting he was followed, he hailed a hansom, and drove away in the direction of Spring Street. Gorby was rather perplexed at this sudden move, but without delay, he hailed another cab, and told the driver to follow the first till it stopped.
"Two can play at that game," he said, settling himself back in the cab, "and I'll get the better of you, clever as you are – and you are clever," he went on in a tone of admiration, as he looked round the luxurious hansom, "to choose such a convenient place for a murder; no disturbance and plenty of time for escape after you had finished; it's a pleasure going after a chap like you, instead of after men who tumble down like ripe fruit, and ain't got any brains to keep their crime quiet."
While the detective thus soliloquised, his cab, following on the trail of the other, had turned down Spring Street, and was being driven rapidly along the Wellington Parade, in the direction of East Melbourne. It then turned up Powlett Street, at which Mr. Gorby was glad.
"Ain't so clever as I thought," he said to himself. "Shows his nest right off, without any attempt to hide it."
The detective, however, had reckoned without his host, for the cab in front kept driving on, through an interminable maze of streets, until it seemed as though Brian were determined to drive the whole night.
"Look 'ere, sir!" cried Gorby's cabman, looking through his trap-door in the roof of the hansom, "'ow long's this 'ere game agoin' to larst? My 'oss is knocked up, 'e is, and 'is blessed old legs is agivin' way under 'im!"
"Go on! go on!" answered the detective, impatiently; "I'll pay you well."
The cabman's spirits were raised by this, and by dint of coaxing and a liberal use of the whip, he managed to get his jaded horse up to a pretty good pace. They were in Fitzroy by this time, and both cabs turned out of Gertrude Street into Nicholson Street; thence passed on to Evelyn Street and along Spring Street, until Brian's cab stopped at the corner of Collins Street, and Gorby saw him alight and dismiss his cab-man. He then walked down the street and disappeared into the Treasury Gardens.
"Confound it," said the detective, as he got out and paid his fare, which was by no means a light one, but over which he had no time to argue, "we've come in a circle, and I do believe he lives in Powlett Street after all."
He went into the gardens, and saw Brian some distance ahead of him, walking rapidly. It was bright moonlight, and he could easily distinguish Fitzgerald by his light coat.
As he went along that noble avenue with its elms in their winter dress, the moon shining through their branches wrought a fantastic tracery, on the smooth asphalte. And on either side Gorby could see the dim white forms of the old Greek gods and goddesses – Venus Victrix, with the apple in her hand (which Mr. Gorby, in his happy ignorance of heathen mythology, took for Eve offering Adam the forbidden fruit); Diana, with the hound at her feet, and Bacchus and Ariadne (which the detective imagined were the Babes in the Wood). He knew that each of the statues had queer names, but thought they were merely allegorical. Passing over the bridge, with the water rippling quietly underneath, Brian went up the smooth yellow path to where the statue of Hebe, holding the cup, seems instinct with life; and turning down the path to the right, he left the gardens by the end gate,
