John Dickson Carr: She Died a Lady (UK 2019)

From the Publisher:
Rita Wainwright's love affair with Barry Sullivan is flamboyant enough to deserve a dramatic ending, so that when the pair of them vanish over a cliff one rainy night, leaving a farewell note for Rita's husband, no one doubts for a moment that it is a case of suicide -- except for Doctor Luke, one of the few people who genuinely liked her. Sir Henry Merrivale -- the fabulous 'H.M.' -- is staying in the area, having his portrait painted as a Roman senator. Although confined to a bath-chair with an injured toe, this does not stop him getting about -- occasionally in toga and laurels -- and solving what is too much for the sharp-eyed doctor.
