Margaret Thomas insisted that her husband's body be ready for burial 36 hours after his death. She inherited roughly £800,000. The Metropolitan Police did not investigate Dr. T. W. Andrew, nor did they investigate the nurse whom Margaret had hired, who was previously linked to the arsenic poisoning of a former employer. Four months later, on 22 August 1898, Rosenblum married Margaret Thomas at Holborn Registry Office in London. The two witnesses at the ceremony were Charles Richard Cross, a government official, and Joseph Bell, an Admiralty clerk. Both would eventually marry daughters of Henry Freeman Pannett, an associate of William Melville. The marriage not only brought the wealth which Rosenblum desired but provided a pretext to discard his identity of Sigmund Rosenblum; with Melville's assistance, he crafted a new identity: "Sidney George Reilly". This new identity was key to achieving his desire to return to the Russian Empire and voyage to the Far East. Reilly "obtained his new identity and nationality without taking any legal steps to change his name and without making an official application for British citizenship, all of which suggests some type of official intervention." This intervention likely occurred to facilitate his upcoming work in Russia on behalf of British intelligence.
