Mrs. Haldane, one of the victims of a mysterious strangler, had a very busy dressing table. Among her perfumes, there’s a bottle of Californian Poppy, a fragrance by Josephine Kell Ltd. The picture above refers to the 1940s version of the perfume, while the bottle seen in the tv show has a different shape and a different lettering on the front label.
The round bottle in front of Californian Poppy is the eau de cologne version of Worth Je Reviens, a floral aldehyde fragrance created by Maurice Blanchet and launched in 1932.
The brown tube looks like Crabtree & Evelyn Gardeners hand therapy cream.
There’s also a refillable atomiser of Rochas Madame Rochas.
Thanks to Jennifer for the hand cream id and to Nastja for the Worth id.
