After attending a private ball hosted at Kensington Palace, Arthur thought it would be difficult to receive another invitation from them in the near future.
Unexpectedly, just a week later, he received an invitation from the Duchess of Kent.
In her letter, the Duchess lavished praise on Arthur's outstanding contributions to society, and stated that the purpose of inviting him to Kensington Palace this time was mainly to introduce her and Princess Victoria to the latest developments in the field of Natural Philosophy. She also expressed interest in Arthur's travels throughout Europe and the latest criminal investigation techniques from Scotland Yard.
In short, what Arthur introduces at Kensington Palace is not important, but his acceptance of the invitation and willingness to visit is extremely important.
With such courtesy from the Duchess of Kent, Arthur had no reason to refuse.
For this, he even canceled a poker game with Talleyrand, the French Envoy.
