There are many Guerlain perfumes on the vanity table of one of Émile’s victims. From left to right:

The classic flacon abeilles contains Eau de Cologne Impériale, a cologne created by Pierre François Pascal Guerlain for Empress Eugenie in 1853.

No way to know what the flacon goutte contains here. This bottle, first launched in the 1920s, has been used for many eaux de toilette.

There’s another flacon abeilles – sans golden bees – containing an eau. The front label is not shown, so it’s impossible to say what eau this is.

The sage green disk on a flacon montre indicates its content: Chypre 53 eau de cologne. The perfume was first released in 1909, but in 1948 it was re-issued as a cologne.

The last bottle is the perfumed deodorant of Chant d’Arômes, a 1962 creation by Jean-Paul Guerlain.
