In effect of an unexpected turn of events, Sylvie will end up on the count's yacht. Additionally she just started suspecting that the count is in fact the person about who she should be very careful. The man asked for tea, so go to the mess (right). There is a thermos with tea on the right and a cup. Take them and (in the inventory) pour the tea into the cup. Take a look at the cupboard (beneath Sylvie's legs; zoom), open the door and take the sleeping pills. Of course put them into the cup of tea.
Now check the drawer on the left (zoom) and take the canned meat from the upper shelf. Eventually take the tin opener from the drawer to the left of the cooker.
Return to the room (left) and to the door (zoom) behind which the count disappeared. Open them slightly and put the tea on the cupboard behind them.
Move to the stairs (left) and check the cubby in the wall. Take everything from it: a sip line, screwdriver and resinous glue. Go to the mess and use the glass door on the right to get to the bridge.
Approach the radio (in the right corner; zoom) and report to the police about your suspicions about the count (you just need to click the radio lid). After finishing, take screwdriver, take out the screws, tear out the cables and put the lid back on. Put the screws back in. Go back to the room and take a look into the count's cabin - it turns out that he hasn't touched the tea. Sylvie has to somehow lure him out.
Go back to the bridge and take a look at the control panel (zoom). Change the ship's course (you just have the click on the middle screen - "helm"). Afterwards go inform the count about it. This way Sylvie will gain free access into his cabin.
Take a look at the desk on the left (zoom). Take the tools lying on the black case: brush, spatula and a magnifying glass. Open the drawer on the right and take the pistol. Go to the bridge. Talk with the count about your suspicions, his amnesia and trust.
Sylvie will want to repair the jug taken from Fatima. Go to the room, take the count's stick leaned against the railing on the right. Approach the table (zoom), on which the jug is.
It's dirty, so clean it with the spatula and brush. Afterwards put some glue on the crack and attach the lid copy. Eventually bind with the cables taken out of the radio and take the antic jug from the table.
