Her death was sudden, after a few days' illness; and she was seized with the malady upon drinking a glass of succory water.

Strong suspicions of poison arose in the court of France, and were spread all over Europe; and as her husband had discovered many symptoms of jealousy and discontent on account of her conduct, he was universally believed to be the author of the crime.
Charles himself, during some time, was entirely convinced of his guilt; but upon receiving the attestation of physicians, who, on opening her body, found no foundation for the general rumor, he was, or pretended to be, satisfied.

The duke of Orleans indeed did never, in any other circumstance of his life, betray such dispositions as might lead him to so criminal an action; and a lady, it is said, drank the remains of the same glass, without feeling any inconvenience.

The sudden death of princes is commonly accompanied with these dismal surmises; and therefore less weight is in this case to be laid on the suspicions of the public.
Charles, instead of breaking with France upon this incident, took advantage of it to send over Buckingham, under pretence of condoling with the duke of Orleans, but in reality to concert further measures for the projected war.

Never ambassador received greater caresses.
