Besides losing his commission, Cornet Heald had, in his marriage, all unwittingly laid up a peck of fresh trouble for himself. This was brought to a head by the action of his spinster aunt, Miss Susannah Heald, who, until he came of age, had been his guardian. Suspecting Lola of a "past," she set herself to pry into it. Gathering that her nephew's inamorata had already been married, she employed enquiry agents to look into this previous union and discover just how and when it had been dissolved. They did their work well, and reported that the divorce decree of seven years earlier had not been made absolute, and that Lola's first husband, Captain James, was still alive. Armed with this knowledge, Miss Heald hurried off to the authorities, and, having "laid an information," had Lola Montez arrested for bigamy.

The case was heard at Marlborough Street police court, with Mr. Bingham sitting as Magistrate. Mr. Clarkson conducted the prosecution, and Mr. Bodkin appeared for the defence.

"The proceedings of a London police court," declared John Bull, "have seldom presented a case more fruitful of matter for public gossip than was exhibited in the investigation at Marlborough Street, where the mediated wife of a British officer (and one invested with the distinction of Royal favouritism) answered a charge of imputed bigamy.... It will readily be inferred that we allude to that extraordinary personage known as Lola Montez, alias the Countess of Landsfeld."

Lola had, as the theatrical world would put it, dressed for the part. She had probably rehearsed it, too. She wore, we learn, "a black silk costume, under a velvet jacket, and a plain white straw bonnet trimmed with blue ribbons." As became a countess, she was not required to sit in the dock, but was given a chair in front of it. "There," said a reporter, "she appeared quite unembarrassed, and smiled frequently as she made a remark to her husband. She was described on the charge sheet as being twenty-four years of age, but in our opinion she has the look of a woman of at least thirty."

"In figure," added a second occupant of the press box, "madam is rather plump, and of middle height, with pale complexion, unusually large blue eyes and long black lashes. Her reputed husband, Mr. Heald, is a tall young man of boyish aspect, fair hair and small brown moustachios and whiskers. During the whole of the proceedings he sat with the Countess's hand clasped in his, occasionally giving it a fervent squeeze, and murmuring fondly in her ear."

All being ready, Mr. Clarkson opened the case for the prosecution.

"The offence imputed to the lady at the bar," he said, "is that, well knowing her husband, Captain Thomas James, was still alive, she contracted another marriage with this young gentleman, Mr. George Trafford Heald. If this be established, serious consequences must follow, as I shall prove that the Ecclesiastical Court merely granted a decree a mensa et thoro." He then put in a copy of this document, and pointed out that, by its provisions, neither party was free to re-marry during the lifetime of the other. Counsel also submitted an extract from the register of the Hanover Square church, showing that, on July 19, the defendant had, under the name of "Maria Torres de Landsfeld," gone through a ceremony of marriage with Cornet Heald.

Police-sergeant Gray, who had executed the warrant, described the arrest.

"When I told her she must come along with me, the lady up and said: 'This is all rubbish. I was properly divorced from Captain James by Act of Parliament. Lord Brougham was present when the divorce was granted. I don't know if Captain James is still alive or not, and I don't care a little bit. I was married to him in the wrong name, and that made the whole thing illegal.'"

"Did she say anything else?" enquired the magistrate.
